Step-by-step explanation:
Trigonometry Identities
Practice Questions From Class 10 Trigonometry IdentitiesProve √(sec θ – 1)/(sec θ + 1) = cosec θ – cot θ
Practice Questions From Class 10 Trigonometry IdentitiesProve √(sec θ – 1)/(sec θ + 1) = cosec θ – cot θProve (tan θ + sec θ – 1)/(tan θ – sec θ + 1) = (1 + sin θ)/cos θ
I hope this answer is helpful for you...

Trigonometric Identities of Opposite Angles
• Sin (-θ) = – Sin θ
•Cos (-θ) = Cos θ
•Tan (-θ) = – Tan θ
•Cot (-θ) = – Cot θ
•Sec (-θ) = Sec θ
•Csc (-θ) = -Csc
generally these are useful..
