is this correct? (integral)

ionic knot

you did the second part wrong

#

it will be integral sinx there

For the first integral, the integral of -cos(x) is -sin(x)+c and the two negatives cancel out, leaving you with +sin(x)+c, so the answer to the first problem is -x*cos(x)+sin(x)+c

#

For the second, ( I assume you are using int udv = uv-intduv) i think there is a problem with your -intduv, since you have x^3/31/x, which is x^2/3
