Question

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

Answer 1

Answer:

we have here

Step-by-step explanation:

cosθ[1−sinθ1−1+sinθ1]=ktanθ

cosθ[1−sin2θ1+sinθ−1+sinθ]=ktanθ

cosθcos2θ2sinθ=ktanθ

2tanθ=ktanθ

k=2

Hence, this is the answer.
