Answer:
a) tan²(∅) - sin²(∅)
Step-by-step explanation:
Write tan²(∅) as sec²(∅)-1 and solve.
--
We have, tan²(∅).sin²(∅)
= [sec²(∅)-1].sin²(∅)
= sec²(∅).sin²(∅) - sin²(∅)
= sin²(∅)/cos²(∅) - sin²(∅)
= tan²(∅) - sin²(∅).
Identities used:
- tan²(∅) = sec²(∅) - 1
- sec²(∅) = 1/cos²(∅)
- sin²(∅)/cos²(∅) = tan²(∅)
