Question

sin square x +cos square square

Answer 1

dear
you know,
sinx=p/h
cosx=b/h
also relation between p,b, and h
p^2+b^2=h^2

sin^2x=p^2/h^2
cos^2x=b^2/h^2

sin^2x+cos^2x=(p^2+b^2)/h^2=1

Answer 2

sin^2(x) + cos^2(x)

= (P/h)^2 + (b/h)^2

= (p^2/h^2) + (b^2/h^2)

= (p^2 + b^2)/h^2

= h^2/h^2

= 1
