Question

Prove that: (cosec - sin o) (sec 0 - cos 0) (tan 0 + coto) = 1
​

Answer 1

Answer:

sin2 a + cos2 a = 1

1+tan2 a = sec2 a

cosec2 a = 1 + cot2 a

Sin θ = 1/Cosec θ or Cosec θ = 1/Sin θ

Cos θ = 1/Sec θ or Sec θ = 1/Cos θ

Tan θ = 1/Cot θ or Cot θ = 1/Tan θ

These are the identities that you must learn
