Question

If tan theata=1/5 what is the value of cosent2 theata- sec2theata/cose2 +sin2

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Ɡiven

tanθ =1/5

by phythogorous theorem

sinθ=1/√26

cosθ=5/√26

i think your question is

(cosec2θ-(sec2θ/cos2)+sin2θ

=>(1/sin2θ)-(1/cos²2θ)+sin2θ

=>(cos²2θ-sin2θ+sin²2θ.cos²2θ)/sin2θ.cos²2θ

=>(cos²θ-sin²θ-2sinθ.cosθ
