If a sin^(3)x+b cos^(3)x= sin x cos x and a sin x= b cos x then a^(2)+b^(2)=

If a sin^(3)x+b cos^(3)x=sin x cos x and a sin x=b cos x then a^(2)+b^(2)=

int(a sin^(3)x-b cos^(3)x)/(sin^(2)x cos^(2)x)dx

int(a sin^(3)x+b cos^(3)x)/(sin^(2)x cos^(2)x)dx

Eliminate x and y from the following equations : a sin ^(2)+ b cos^(2) x=c, b sin ^(2) y+ a cos^(2) y=d, a tan x= b tan y .

If y= tan ^(-1) ((a cos x- b sin x )/(b cos x + a sin x ) ) , then (dy)/(dx) is :

" if "A=[[cos^(2)x,sin^(2)x],[-sin^(2)x,-cos^(2)x]]" and "B=[[sin^(2)x,cos^(2)x],[-cos^(2)x,-sin^(2)x]]" then find "A+B"
