Question

Simplify.

1/cosθ + tan^2θ/cosθ

• 1 + sinθ
• sec^3θ
• 1
• cos^3θ

Answer 1

Answer:

I'm guessing the answer is sec³θ

Step-by-step explanation:

I tried this problem and I got 1/cos³θ and clicked cos³θ, but that answer was incorrect. In my lesson, there were the options:

1. sec³θ

2. cos³θ

3.  secθ

I didn't have options 1 + sinθ or 1 as answers. If sec³θ is not the correct answer, please correct me.
