The trig ratios are "sine, cosine, tangent, secant, coscant, and cotangent" which gives us a total of 6 trig ratios to work with.

While most people are use to dealing with degrees as the measurement for angles, the most common measurement in mathmatics is actually Radians. Radians is base on a circle that measures as 2PI radians.

Radians are based around a circle that measures as 2PI radians.

Tangent's Range covers all real numbers. Sine and Cosine both have a limited range.

45 degrees in Radians is known as PI/4. The easy way to convert this, is to use your conversion formulas. 45 * PI/180 since we are going to radians it should be PI on top and 180 on bottom. If we were to convert from Radians to degrees, you would multiply by 180/PI.
