Question

If tanA=b/a, where a and b are real numbers.Find sin^2A.

Answer 1

@mathstudent55 - I got till that step! My doubt is that should i just leave it like that or can i simplifiy? Thanks.

Answer 2

a^2 + b^2 = c^2
If tanA = b/a, then sinA = b/c
sin^2A = b^2/c^2
sin^2A = b^2/(a^2 + b^2)

Answer 3

I think this is it. The answer is in terms of a and b, like the given information.

Answer 4

Thanks a lot!! :D
