Question

prove cosec theta root 1-cos^2 theta =1​

Answer 1

Explanation:

refe to the attachment.....

hence proved

Answer 2

Hence proved 1 - $cos^{2}$θ = $sin^{2}$ θ

Explanation:

Using the identity 1 - $cos^{2}$θ = $sin^{2}$ θ

Cosec θ = 1/sin θ

To prove,

Cosec θ ×$\sqrt{1 - cos^{2}}$θ = 1

Cosec θ ×$\sqrt{1 - cos^{2}}$θ

Cosecθ × $\sqrt{sin^{2} }$θ

1/sinθ × sinθ = 1

= R.H.S
