Step-by-step explanation:
Answer:
or .
Step-by-step explanation:
How are tangents and secants related to sines and cosines?
.
.
Sticking to either cosine or sine might help simplify the calculation. By the Pythagorean Theorem, . Therefore, for the square of tangents,
.
This equation will thus become:
.
To simplify the calculations, replace all with another variable. For example, let . Keep in mind that .
.
.
Solve this equation for :
.
