Answer:
secФ = ±[tex]\sqrt{1+tan^{2} }[/tex]
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: [tex]\sqrt{sec^{2} } =\sqrt{1+tan^{2} }[/tex] which then simplifies to
- secФ = ±[tex]\sqrt{1+tan^{2} }[/tex]
