The derivative of function f (x) = 2x + 1 is The wrong number should be this one The derivative of y = x Λ 2lg2 + 2 Λ xlgx

The derivative of function f (x) = 2x + 1 is The wrong number should be this one The derivative of y = x Λ 2lg2 + 2 Λ xlgx

y=x²lg2+2^xlgx
y`=(x²lg2)`+(2^xlgx)`
=lg2(x²)`+(2^x)`lgx+2^x(lgx)`
=2xlg2+2^xln2lgx+2^x/(xln10)
y=x^2lg2+2^xlgx
y'=2lg2x^(2lg2-1)+2^xlgx*ln2*(lgx+x/x*ln10)
=2lg2x^(2lg2-1)+2^xlgx*ln2*(lgx+ln10)
What are the meanings of prime, composite, multiple and factor?
Prime number
Prime number is also called prime number. The number of prime numbers is infinite. Composite number: the divisor of a number has other divisors besides 1 and itself, which is called composite number. 2 is not composite number, 1 is neither prime nor composite number. Prime factor is the divisor of a composite number, and these divisors are prime numbers
Multiple, factor
In division, if the divisor is divided by the divisor, the quotient obtained is a natural number with no remainder, it is said that the divisor is a multiple of the divisor, and the divisor is a factor of the divisor

Let f (x) be the original function of F (x), then the derivative of F (2x) is
F'(x)=f(x)
F'(2x)=f(2x)*(2x)'
=2f(2x)
What are the meanings of factors, multiples, prime numbers and composite numbers?
Factor:
If 3 times 2, 3 and 2 are factors
multiple:
If 6 divided by 3 equals 2, then 6 is twice of 3
Prime number:
Such as 2, 3, 5, 7, 11, 13, 17, 19
These numbers are prime numbers with no other factors except 1 and itself
Total number:
Such as 4, 6, 8, 9, 10
These numbers with three or more factors are called composite numbers
1 is neither prime nor composite
The definition of derivative: Lim [f (2x) - f (x)] / x = a, find f (0) '
Can {x tends to 0} Lim [f (2x) - f (x)] / x = a do this? The original formula = Lim [f (x + x) - f (x)] / x = a, so according to the definition of derivative f (0) '= a
No. It should be divided into Lim [f (2x) - f (0)] / x-lim [f (x) - f (0)] / x = 2F & # 39; (0) - F & # 39; (0) = F & # 39; (0); & nbsp; F & # 39; (0) = a

Prime factor is divisor: the factor of a composite number, and these factors are prime multiples, factors
Given f (x) = 2x + 3, we can find f '(2), f' (x) with the definition of derivative
analysis
f'(x)=2
So whatever the value of X is
It's all two
f'(2)=2
f'(x)=2
Children's shoes
The limit of (f (2 + x) - f (2)) / X when x tends to 0
What do factors and multiples mean?
After this evening, there will be no additional Da!
For example, 24 divided by 6 equals 4. We say that 24 is the multiple of 6 and 4. 6 and 4 are the factors of 24. Factors and multiples are interdependent and cannot exist in isolation. If 24 cannot be said to be a multiple, it is necessary to clarify whose multiple it is. In addition, when we study factors and multiples, we usually do not consider 0
F (2x) = INX
Let t = 2x, then x = t / 2
So f (2x) = f (T) = ln (T / 2)
So f (x) = ln (x / 2)
So f '(x) = (LN (x / 2))'
=1/(x/2) * (x/2)'
=2/x * 1/2 =1/x
F (x) = ln (x / 2)
f'(x)=(ln(x/2))'(x/2)'
=(2/x)*(1/2)
=1/x
The meaning of factor and multiple
It's the meaning
An integer is divided by another integer, which is the factor of the former
Example: 6 △ 2 = 3, 2 and 3 are the factors of 6
If an integer can divide another integer, this integer is a multiple of another integer. For example, 15 can be divided by 3 or 5, so 15 is a multiple of 3 and also a multiple of 5
② The quotient of a number divided by another number. For example, a △ B = C, that is to say, a is a multiple of B and a is a multiple of B
If a factor divides his product, then the number is a factor and his product is a multiple
3 × 5 = 15
↑ ↑ ↑
Factor 1 factor 2 multiple
For example: a △ B = C, it can be said that a is c times of B
③ There are innumerable multiples of a number, that is to say, the set of multiples of a number is infinite
