Frequently Asked Questions

Why use radians instead of degrees?
Radians are the natural measure of angles in mathematics. Arc length equals radius times angle in radians, which simplifies many formulas.
How many radians are in a full circle?
A full circle contains 2π radians, which equals 360 degrees.
What are the exact sin and cos values for common angles?
0°: sin=0, cos=1; 30°: sin=1/2, cos=√3/2; 45°: sin=√2/2, cos=√2/2; 60°: sin=√3/2, cos=1/2; 90°: sin=1, cos=0
What are cotangent, secant, and cosecant?
cot = cos/sin (cotangent), sec = 1/cos (secant), csc = 1/sin (cosecant) - these are reciprocal trigonometric functions.
When is tangent undefined?
Tangent is undefined when cosine equals zero, which occurs at 90°, 270°, and other odd multiples of 90°.
