Use the fact that cos(z) = R(e^{iz}) = (e^{iz} + e^{-iz})/2 to find the integral of (e^{3x}cos(4x))dx.

Step 1

Here the given integral in not in the complex form so we calculate the integral as it is given in the question:

Step 2

Here we integral the function in the by applying the integration by parts:

Step 3

Again do the integration by parts in ...
