The first problem is...
y = 1/2 e^x - 3 sinx
Derivative = 1/2e^x - 3 cosx * 1
Is that right? I wasn't sure about the 1/2.
The second problem I have is...
f(x) = (2e^x)/(x^2 + 1)
I am not sure what the derivative of 2e^x is...is it just 2e^x?
(x^2 + 1)(2e^x) - (2e^x)(2x)/(x^2 + 1)^2
We don't have to simplify.
