What is Tangent?

In trigonometry, the tangent of an angle (\( \tan(θ) \)) is defined as the ratio of the sine of the angle to the cosine of the angle:

\[ \tan(θ) = \frac{\sin(θ)}{\cos(θ)} \]

The tangent function is periodic and has asymptotes where the cosine of the angle equals zero, such as at \( 90^\circ \) or \( \frac{\pi}{2} \) radians. The tangent function is widely used in mathematics, physics, engineering, and computer graphics.
