Question

1. show that cos theata×[(1/1-sin theata)-(1/1+sin theata)] can be written in the form k tan theata and find the value of k.​

Answer 1

Answer:

Answer

We have,

cosθ[1−sinθ1−1+sinθ1]=ktanθ

cosθ[1−sin2θ1+sinθ−1+sinθ]=ktanθ

cosθcos2θ2sinθ=ktanθ

2tanθ=ktanθ

k=2

Hence, this is the answer.
