Homework Statement
[tex]\int2e^-^7^xdx[/tex]
Homework Equations
None
The Attempt at a Solution
[tex](\frac{-2}{7})(\frac{e^-^7^x}{-7})+C[/tex]
This is as far as I can go, but the answer is:
[tex]\frac{-2e^-^7^x}{7}+C[/tex]
So, why do you have 1/7 * 1/7? Just do it again from scratch and you'll probably see what you did wrong.I took the antiderivative of [tex]e^-^7^x[/tex].
