Im reviewing for an exam and cant figure out this question..
what is y' of x^2/2 + 2/x^2 +pi (not sure pi symbol on here)
I know that pi is a constant so its prime is 0, and because this is an old test I know the answer is x^4-4/x^3, getting to that is another problem
the second term i changed to 2x^-2, which gives me the x^3 in the bottom of the answer, but i cant figure this out.
Another that is stumping me is y' of (1+2x)e^3x
I was able to work it that far, and I see how -4 is part of the top, and x^3 is part of the bottom, I just cant figure how x^2/2 works out to be x^4. the derrivitive of x^2 should be 2x shouldnt it?
I just worked through the second question I posted (1+2x)e^3x, simple once i remembered to factor out the e^3x's
