What angle is Sine and cosine equal?
at a 45 degree angle, or pi/4
What angles have the same inverse cosine?
Given an angle A, the angle (2pi - A) has the same cosine. So do the angles that differ from these by 2k*pi radians for all integers k. If you are still working in degrees, you should substitute 180 degrees for pi radians.
When is secant not defined?
The secant of an angle is the reciprocal of the cosine of the angle. So the secant is not defined whenever the cosine is zero That is, whenever the angle is a multiple of 180 degrees (or pi radians).
How do you find the cosine and the sine?
Sine= Opposite/ Hypotenuse Cosine= Adjacent/ Hypotenuse
