Find the integral of sinx.sin2x.sin3x w.r.t. x

You may also abbreviate the answer, iterating to ultimately...1/4[cos6x/6-cos4x/4+cos2x/2)] + constant
To mention, the obvious increasing order of co-efficient to sin, mapps somewhere to the decreasing coeff orders arranged in cos, where somewhere all the time in operation is the available substitution, sinx = 1-cosx.

Hi aiesha Please reply if satisfied with my solution.
Hello erkamath. May I ask you if you have a way to reach the answer if you had to operate 3 substitutions? I mean, could you break it down to eg ;u.v.w. where each are a factor of the total amount/polynomial.perhaps if as you suggest in rearrangement the answer will reach by performing w.u.v to rearrange as desired....Your opinion would be appreciated,M.

When you apply u.v.w , it become complexThere is a short cut method also but for which in depth knowledge is required
erkamathYour solution really helped methankyou
Most welcome aiesha
sorry, thought that was a comma
could teach me for this problem please? for the equation f(x) = 5/6x2/3+2/3x1/2+6x2+12 find the integral of this question.
