What Are Trigonometric Ratios?
Trigonometric ratios (sine, cosine, tangent) give the side ratios of an angle in a right triangle. They are used in angle and distance calculations.
How is it calculated?
How Is It Calculated?
- Enter the angle (in degrees).
- sin = opposite/hypotenuse, cos = adjacent/hypotenuse, tan = opposite/adjacent.
For example, sin 30° = 0,5.
Frequently Asked Questions
Why is tan 90° undefined?
At 90 degrees the adjacent side goes to zero, so the division becomes undefined.
