Best ResponseYou've already chosen the best response.0If f(t)dt=e^(3x)cos(x)0 to x then using the Fundamental Theorem of calculus you get f(t)dt=[e^(3x)cos(x)+c][e^(0)*cos(0)+c]=e^3x*cos(x)1+(cc)=e^3x*cos(x)1. The definite integral doesn't have a constant simply because the c cancels when you subtract.

Best ResponseYou've already chosen the best response.0I think you can simply find the answer by setting x=0 , you will find c=1
