Find the derivative of F (x) = e ^ x-e ^ (- x)!

Find the derivative of F (x) = e ^ x-e ^ (- x)!

f(x)=e^x-e^(-x)
f'(x)
=e^x-[e^(-x)×(-1)]
=e^x+e^(-x)

Even number C can decompose prime factor a
Choice: a combined number
2 is even, but cannot decompose the prime factor
Prime numbers can't be any more
A is a composite number, not an even number, as opposed to a prime number. Even and odd numbers can be prime or composite numbers
A. Total number
Why is the derivative of F (x) = e ^ x + ex e ^ x + e
How to find the derivative of ex?
In y = ex, e ≈ 2.72 is just a constant. According to the derivative formula, the constant term can be directly put forward. Don't confuse it!
y'=(ex)'=e(x)'=e
According to the definition and algorithm of derivative, f ′ (x) = (e ^ x) ′ + (Ex) ′ (f ′ (x) denotes the derivative of F (x))
=lim[e^(x+△x)-e^x]/△x+lim[e(x+△x)-ex]/△x (△x→0)
... unfold
According to the definition and algorithm of derivative, f ′ (x) = (e ^ x) ′ + (Ex) ′ (f ′ (x) denotes the derivative of F (x))
=lim[e^(x+△x)-e^x]/△x+lim[e(x+△x)-ex]/△x (△x→0)
=e^x.lim[(e^△x-1)/△x+e.lim△x/△x (△x→0)
When △ x → 0, e ^ △ x → 1, e ^ △ X-1 → 0, ｜ Lim [(e ^ △ x-1) / △ x = 1, ｜ (e ^ x) ′ = e ^ x
When △ x → 0, Lim △ X / △ x = 1, ｜ (Ex) ′ = E
Ψ f ′ (x) = e ^ x + e
E is a constant (similar to π)
So the derivative of ex is e
So f (x) '= (e ^ x + Ex)' = e ^ x + E
In ex, X is a variable, e is a constant, e = 2.718281828 ·· so the result of derivation of ex is the coefficient before x, e y '= (Ex)' = e (x) '= E
The product of a prime number multiplied by an even number must be ()
A. Odd B. even C. prime
For example: 2 × 4 = 8, 8 is even, 3 × 6 = 18, 18 is even, so the product of prime number multiplied by even number must be even
What is the root of 2.5 to the 10th power
one point zero nine five nine five eight two two six three eight five two one seven two
The product of several prime numbers is () a prime number B composite number C prime factor
Choose the correct answer and fill in the brackets
B
B
B
B
It's B, because except for 1 and itself, the two factors are prime numbers. Because of this factor, it's a composite number, so we should choose B
Is the sixth power of root x equal to the third power of X
Not equal, should be = | x ^ 3|
In 36, even numbers have () prime numbers have () composite numbers have ()
In 36, the even number has (2,4,6,12,18,36) the prime number has (2,3) and the composite number has (4,6,9,12,18,36)
1 is neither prime nor composite
In 36, the even number has (2,4,6,12,18,36) the prime number has (2,3) and the composite number has (4,6,9,12,18,36)
The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18 and 36
Even 2, 4, 6, 12, 18, 36
Prime 2, 3
The total number is 4, 6, 9, 12, 18 and 36
You're right! Like ~ \ (≥ ▽≤)/~
Implicit function xcosy = sin (x + y), find the derivative of y to X
The results show that xcosy sin (x + y) = 0
Y = / DX FX
=-[cosy-cos(x+y)]/[-xsiny-cos(x+y)]
=[cosy-cos(x+y)]/[xsiny+cos(x+y)]
I'm not sure, but I can provide an important knowledge point. The derivative of SiN x is cos x, and the derivative of COS x is - Sin X
Of the factors of 42, prime has______ The total number is______ The odd number has______ Even numbers have______ .
The factors of 42 are: 1, 2, 3, 7, 42, 21, 14, 6. According to the definition of prime, composite, odd and even numbers, among the factors of 42, prime has 2, 3, 7, composite has 6, 14, 21, 42, odd has 1, 3, 7, 21, even has 2, 6, 14, 42.
