Trig Function Value Calculator
The Trig Function Value Calculator gives the sine, cosine, tangent, and their reciprocals for any angle. Enter the angle in degrees to see all six function values.
Formula
Evaluate sin, cos, tan and their reciprocals at the given angle
- Angles are entered in degrees and converted to radians internally.
- tan and sec are undefined where cos = 0; cot and csc where sin = 0.
45°
Inputs
- Angle: 45 °
sin 45° = cos 45° ≈ 0.7071, tan 45° = 1.
Frequently asked questions
