Answer 2

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(∅)
