find the reduction formula of integration( acosx+bainchod)^n
If you mean (acosxdx*bcosxdx)^n the the reduction formula can be calculated as
(sinh^n+1)/(xcosh)^m−1/(n+m)+(m−1)/(n+m)∫sinh^nx * cosh^(m−2)xdx .You can try solving more problems from a reference book or seeing some videos to clear your concepts on reduction formula.
