given  sincot-1tancos-1x

but we know that cos-1x=tan-1(1-x2)1/2/x

= sincot-1tantan-1(1-x2)1/2/x

=sincot-1(1-x2)1/2/x                   (since tantan-1x=x)

=sinsin-1x

=x

therefore  sincot-1tancos-1x=x

I HOPE YOU WILL FIND TIS SOLUTION HELPFUL......

ALL THE BEST FOR YOUR FUTURE....................................
