Differentiating exponential functions in exercise, find the derivative of the function. see example 2 and 3.
f(x) = (e^x + e^-x)4/2

The derivative would be

Step-by-step explanation:

Since we have given that

As we will use "Chain Rule"

and at last we will use the identity ''''

We need to find the derivative of the function:

Hence, the derivative would be

3; 9 is 8 to -4

step-by-step explanation:

good luck on your studies! : )
