Integral from -2 to 3 of e^(2x)cos(3x)dx I think I am suppose to solve for the unknown integral using Integration by parts formula however I have tried multiplies times but no luck lol.

Please note that the function has five roots on the interval , ie, this function times changes its sign in this interval. I hope you understand why this is necessary. If you calculate everything correctly, then your response should be approximately equal to .
