The six trigonometric functions are connected through sine and cosine. Once sine and cosine are known, tangent and the reciprocal functions can be computed directly.
⚠Enter the angle in degrees. Some reciprocal values are undefined when sine or cosine is zero.
How Trig Values Work
Sine and cosine come from the unit circle coordinates. Tangent is sine divided by cosine, and the remaining functions are reciprocals.
Primary Functions
sin, cos, and tan are the basic ratios.
Reciprocal Functions
sec, csc, and cot are reciprocal forms.
Undefined Cases
Zero denominators create undefined values.
Unit Circle
Coordinates explain sine and cosine.
💡 Example: For 30°, sin=0.5, cos=0.866025, tan=0.57735, csc=2.
