Question

prove that sin square theta + cos square theta is equal to 1​

Answer 1

HEY MATE YOUR ANSWER IS HERE ^_^

to prove

(sin theeta)^2 + (cos theeta)^2 = 1

perpendicular = p

base = b

hypotenuse = h

proof

sin theeta = p/h

cos theeta = b/h

(sin theeta)^2 + (cos theeta)^2

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

p^2 /h^2 + b^2 /h^2

(p^2 +b^2)/h^2.........(p^2 +b^2=1 by

pythagores theorem)

h^2/h^2 = 1

prooved

please make me a brainlist answer for the question
