Question

Secθ =__________________ 1/sinθ +-√cos^2 +1 +-√tan^2 +1

Answer 1

Answer:

The answer is last option

As we know 1 + tan^2 = sec^2

Answer 2

Answer:

secФ = ±$\sqrt{1+tan^{2} }$

Step-by-step explanation:

We can use the identity sec²Ф = 1 + tan²Ф to solve for secФ

• First we need to take the square root of both sides to get: $\sqrt{sec^{2} } =\sqrt{1+tan^{2} }$ which then simplifies to
• secФ = ±$\sqrt{1+tan^{2} }$
