Question

solve this question to become a brainleist

Answer 1

Here is your solution

cosec A+cot A=p

1/sinA  + cosA/sinA = p

1+cosA = psinA

Squaring both the sides

(1+cosA)^2 = p^2 (sinA)^2

(1+cosA)^2 = p^2 (1-(cos)^2)

(1+cosA)^2 = p^2 (1-(cos)) (1+cosA)

1+cosA = p^2 (1-cosA)

cosA = (p^2-1)/(p^2+1)

Hence proved

hope it helps you
