Best ResponseYou've already chosen the best response.0the answer at the back is 2/3pi cos (3pi/2 + pi/4) +c

Best ResponseYou've already chosen the best response.0Are you sure that it's \[\int sin\left(\frac{3\pi}{2}+\frac{\pi}{4}\right) dx\]?? I think that it's missing a \(x\) somewhere

Best ResponseYou've already chosen the best response.0sin ((3pi/2) + (pi/4)) = sin(pi/4)

Best ResponseYou've already chosen the best response.0Then if you remember your exact values, sin(pi/4) = sqrt(2)/2

Best ResponseYou've already chosen the best response.0So sin(pi/4) = sqrt(2)/2

Best ResponseYou've already chosen the best response.0Then integrate sqrt(2)/2

Best ResponseYou've already chosen the best response.0I mean integrate sqrt(2)/2 with respect to x

Best ResponseYou've already chosen the best response.0You will get integral(sin ( (3pi/2) + (pi/4))) = sqrt(2)/2 x
