What is the tangent of an angle?

The tangent of an angle is the ratio of the opposite side to the adjacent side in a right triangle. It can also be defined as sin(θ) / cos(θ).

Why is it important to select degrees or radians?

The Math.tan function in JavaScript uses radians. If the angle is entered in degrees, it must be converted to radians before the tangent can be calculated.

What are some common tangent values?

Some common tangent values include: tan(0) = 0, tan(π/6) ≈ 0.577, tan(π/4) = 1, tan(π/3) ≈ 1.732. The tangent is undefined at π/2 (90 degrees).

Understanding Tangent

The tangent of an angle in a right triangle is the ratio of the length of the opposite side to the length of the adjacent side. In terms of sine and cosine, tan(θ) = sin(θ) / cos(θ).

Radians vs. Degrees

Angles can be measured in degrees or radians. A full circle is 360 degrees or 2π radians. The conversion between degrees and radians is: radians = degrees * (π / 180).
