Integrate (cosx)(sinx)^3

Announcements Posted on

    I've tried splitting it up into (cosx)(sinx)(sinx)^2, and then using various identities, but that's really long-winded. The shortness of the other questions in the exercise leads me to believe that there is a better way?

    Substitution perhaps?

    cos x is the derivative of sin x, so this is simply a reverse chain rule job, surely?

    Because sinx differentiates to cosx, you just integrate (sinx)^3 to get ((sinx)^4)/4

    It's not that long-winded is it?
    but yeah, just do a simple substitution.
