The derivative of the function y = x & # 178; / x + 3 is y = sin (2x & # 178; + x)

The derivative of the function y = x & # 178; / x + 3 is y = sin (2x & # 178; + x)

y'=[2x(x+3)-x²]/(x+3)²
=(x²+6x)/(x+3)²
y'=cos(2x²+x)·(2x²+x)'
=(4x+1)cos(2x²+x)
solution
y=x²/(x+3)
y'=[(x²)'(x+3)-x²(x+3)'](x+3)²
=[2x(x+3)-x²]/(x+3)²
=(x²+6x)/(x+3)²
y=sin(2x²+4)
y'=[sin(2x²+4)]'
=cos(2x²+4)(2x²+4)'
=4xcos(2x²+4)

A prime number is a prime number. A number with only one and two factors is called a prime number
In addition to one and itself, there are other factors called composite numbers
A number that is a multiple of two is called an even number
Numbers that are not multiples of two are called odd numbers
How to calculate the derivative of function y = Sin & # 178; X / (1 + Cotx) + cos & # 178; / (1 + TaNx)
y=sin^3x/(sinx+cosx)+cos^3x/(cosx+sinx)=(sin^2x-cosxsinx+cos^2x)=1-cosxsinx=1-(1/2)sin2x
So:
y'=-(1/2)(cos2x)*(2)=-cos2x.
The solution function is y = 1 - (1 / 2) sin2x
So:
y'=-(1/2)(cos2x)*(2)=-cos2x.
The precise point of prime combined odd even number definition
Prime number: a number that contains only one and two factors of itself. For example, 11, his factor is only (1, 11)
Composite number: a number containing other factors besides 1 and itself. For example, 10, his factors are (1, 2, 5, 10)
Even numbers (2, 8) can also be divided by even numbers
Odd number (also called singular number): a number that cannot be divided by 2, such as 1, 3, 5, 7
Sin θ, sin 2x, cos θ are arithmetic sequence, sin θ, SiN x, cos θ are proportional sequence, find the value of COS 2x ~ (+ ﹏ +)~
Sin θ, sin 2x, cos θ are arithmetic sequences,
Then 2sin2x = sin θ + cos θ ①
Sin θ, SiNx, cos θ are equal ratio sequence,
Then Sin & # 178; X = sin θ cos θ ②
①²-②×2:
4sin²2x-2sin²x=(sinθ+cosθ)²-2sinθcosθ
∵（sinθ+cosθ)²-2sinθcosθ
=sin²θ+cos²θ+2sinθcosθ-2sinθcosθ
=1
∴4(1-cos²2x)-(1-cos2x)=1
∴4cos²2x-cos2x-2=0
cos2x=(1±√33)/8
What is a prime compound odd even number?
What are prime, composite, odd and even numbers?
Is 1 prime? Is 1 composite? Is 1 odd? Is 1 even?
The ball answers,
Prime numbers are natural numbers with no other factors except 1 and itself; composite numbers are natural numbers with not only 1 and its own factors but also other factors. Odd numbers can not be divided by 2, even numbers can be divided by 2.1, which is neither prime nor composite numbers; but 1 is odd,
Prime numbers are natural numbers with no other factors except 1 and itself; composite numbers are natural numbers with not only 1 and its own factors but also other factors. Odd numbers cannot be divided by 2, even numbers can be divided by 2. 1 is neither prime nor composite, but 1 is odd, so it is not even o (∩)_ ∩)O

Oooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooh
Composite number: a positive integer that can be divided by other positive integers except 1 and itself. Even numbers except 2 are composite numbers. (except 0)
In all integers, except the prime number and the divisor 1, it is no longer called a prime number. It can also be said that a prime number has only one and two divisors of itself.
Odd number: in integers, the number that cannot be divided by 2 is odd. The odd number can be represented by 2K + 1, where k is an integer.
Even number: in integers, the number divisible by 2 is even, and vice versa. Even number = 2K,... Expansion
Composite number: a positive integer that can be divided by other positive integers except 1 and itself. Even numbers except 2 are composite numbers. (except 0)
Prime number (also known as prime number): in all integers larger than 1, except 1 and itself, there is no other divisor. This kind of integer is called prime number or prime number. It can also be said that a prime number has only one and two divisors of itself.
Odd number: in integers, the number that cannot be divided by 2 is odd. The odd number can be represented by 2K + 1, where k is an integer.
Even number: in integers, the number divisible by 2 is even, and vice versa. Even = 2K, odd = 2K + 1, where k is an integer. Put it away
Prime numbers are numbers that can not be divisible except 1 and itself, which correspond to composite numbers, that is, composite numbers are numbers that can be divisible except 1 and itself; odd numbers are this number / 2 and non-zero remainder, while even numbers can be divisible by 2.
A prime number is a prime number. A prime number means that a number has no divisors (factors) other than 1 and itself. This number is called a prime number (prime number is also called a prime number). Such as 2, 3, 5, 7, 13.
Total number
A number has other divisors besides 1 and itself. This number is called composite number. For example: 4, 6, 8, 9, 10
Note: 1 has only one divisor, which is itself. 1 is neither prime nor composite. It is the basic unit of natural number and the smallest natural number.
The smallest prime number is 2, which is the only expansion of prime number
A prime number is a prime number. A prime number means that a number has no divisors (factors) other than 1 and itself. This number is called a prime number (prime number is also called a prime number). Such as 2, 3, 5, 7, 13.
Total number
A number has other divisors besides 1 and itself. This number is called composite number. For example: 4, 6, 8, 9, 10
Note: 1 has only one divisor, which is itself. 1 is neither prime nor composite. It is the basic unit of natural number and the smallest natural number.
The smallest prime number is 2, which is also the only even number in the prime number (see the explanation of even numbers below), and the rest of the prime numbers are odd numbers (see the explanation of odd numbers below).
3. Even number
Even numbers are natural numbers (including 0) divisible by 2, also called even numbers. Even numbers are usually represented by "2K".
4. Odd number
Odd numbers are natural numbers that cannot be divided by two, also called singular numbers. Odd numbers are usually represented by 2K + 1
Note: even numbers are composite except 2. Put it away
Prime numbers are integers that have no divisors other than 1 and themselves
In addition to the divisor itself, there are also divisors of 1
Odd and even numbers are integers that cannot be divisible by 2 and divisible by 2, respectively
1 is neither a prime number (also called a prime number), nor a composite number, but an odd number.
Prime numbers are divisors with only 1 and their own numbers. Composite numbers refer to the numbers in the positive integer except prime numbers. Odd numbers are singular numbers and even numbers are even numbers
1 is not prime, 1 is not composite, 1 is odd, 1 is not even
A prime number (also called a prime number) is a number that has only one and two factors of its own
In addition to 1 and itself, there are other factors called composite numbers. 1 is neither prime nor composite
The number that can be divisible by 2 is called even, the number that cannot be divisible by 2 is called odd, and 1 is odd.
"1" is neither a prime nor a composite number! And your "ball" is wrong. It should be "Qiu". Hehe, you're great. I know how to search online! GOOD！ come on.
It is known that it belongs to (0, Pai / 2), and SiNx and cosx are the mean of equal difference and the mean of equal ratio of sina and cosa, respectively
1/2(sina+cosa)=sinx
(sina*cosa)^(1/2)=cosx
The solution is x = pi / 4
Concepts of prime number, composite number, odd number and even number
Even number (also called even number): a number divisible by 2, such as 0, 2, 4, 6, 8, 10
Odd number (also called singular number): a number that cannot be divided by 2, such as 1, 3, 5, 7, 9
