Explanation / Answer

x = r cos ? y = r sin ? dA = r d? dr Your integral becomes ?? (r sin ?) e^(r cos ?) r dr d? Integrate over ? first by letting u=r cos ?, du = -r sin ?, and u varies from r cos 0 to r cos p/2 = r to 0: = ? -r [ ? e^u du ] dr = ? -r [e^0 - e^r] dr = ? re^r dr - ? r dr The right integral is easily r²/2 from r=0 to 4, or 4²/2 = 8 Integrate the left by part, using v*dw with v=r and dw = e^r dr, so dv = 1 and w = e^r. ? v dw = vw - ? w dv = r e^r - ? e^r dr = (r - 1)e^r evaluated from r=0 to r, which is 3e^4 - (-1)e^0 = 3e^4 + 1
