Question

sin^2A+sin^2B =1 prove it

Answer 1

Hey friend ..

As you know that in right angle triangle there is 3 side , heipotenous h` base `b and p perpendicular.

So, by using Pythagoras theorem you know

h²=p²+b²----------1)

and, now you know sin¢=p/h
and ,
cos¢=b/h

so,, now putting this value on

sin²¢+cos²¢

=(p/h)²+(b/h)²

=p²+b²/h²

=h²/h². {by using 1 . equation}

=1 RHS prooved .

hope it helps you .
