Question

prove sin^2x + cos^2x = 1

Answer 1

Helloo!! 

the branch of science concerned with the bodily structure of humans, animals, and other living organisms, especially as revealed by dissection and the separation of parts

Hope it helps

Answer 2

W.K.T sin x = opposite side/hypotenuse, cos x = adjacent side/hypotenuse.

sin^2 x + cos ^2 x :  

= (opposite side/hypotenuse)^2 + (adjacent side/hypotenuse)^2

= ((opposite side)^2 + (adjacent side)^2) / (hypotenuse)^2

= (hypotenuse)^2 / (hypotenuse)^2

= 1.


Hence proved. sin^2 x + cos ^2 x = 1
