Question

Prove that
tan² thita - 1/cos² thita = -1

solve it step by step
​

Answer 1

Answer:

tan² thita - 1/cos² thita

sin² thita/cos² thita - 1/cos² thita

sin² thita - 1 / cos² thita                             [ sin² thita + cos² thita = 1

- cos² thita/cos² thita                                  cos² thita = 1 - sin² thita

- 1                                                                  cos² thita = sin² thita - 1 ]
