Question

find the value of 6 tan square theta minus 6 upon cos square theta​

Answer 1

Answer:

Hey friend, Harish here.

Here is your answer.

⇒ sec θ = cos²θ

⇒ 1/cosθ  = cos²θ

⇒ cos³ θ = 1

⇒ cos θ = 1

So, θ = 0 degrees

Now substituting the value we will get answer as :

sin⁴ 0° + 2 sin³ 0° + sin² 0°

⇒ 0⁴ + 2 (0³) + 0² = 0
