solve the differential equation
integral of e^x=e^x
The Attempt at a Solution
im not really sure how to do it when there are two variables in the exponent? i tried several things like u=x^2 1/2du=xdx then 1/2*int[e^a*u] results, but i can't take the integral without a different substitution since int[e^a*u] is not = to e^a*u.
the answer is 1/2a * e^ax^2 + C.. any methods to integrate this? several methods would be best
