tan

Computes the tangent in radians for each element of x.

📝 Syntax

• res = tan(x)

📥 Input argument

• x - a numeric value

📤 Output argument

• res - a numeric value

📄 Description

tan computes the tangent in radians for each element of x.

The tangent function is defined as: $\tan(x) = \frac{\sin(x)}{\cos(x)} = \frac{e^{ix} - e^{-ix}}{i(e^{ix} + e^{-ix})}$

It has vertical asymptotes at $x = \frac{\pi}{2} + n\pi$

for integer n.

💡 Example

A = eye(3, 3);
res = tan(A)
