Question 40904: Please help....
Explain why tan(x + 450 degrees) cannot be simplified using the tangent sum formulas, but can be simplified by using the sine and cosine formulas. Give examples.
I do know that Tan(x+450)cannot be simplified using the tangent sum formula because it cannot be divided by zero.
Answer by fractalier(6550) (Show Source): You can put this solution on YOUR website!
tan(x + 450) = sin(x + 450) / cos(x + 450) = sin(x + 90) / cos(x + 90) =
[sin x cos 90 + sin 90 cos x] / [cos x cos 90 - sin x sin 90] =
cos x / -sin x =
- cot x
