 Solving Domain Set R (Reals) Z (Integers) C (Complex)

## Answers to Questions (FAQ)

### What is a trigonometric equation?

A trigonometric equation is a mathematical expression with an equality between two elements containing unknown variables and trigonometric functions (cos, sin, tan, etc.).

Example: $\cos(x) = sin(\pi)$

### How to solve a trigonometric equation?

dCode automatically solves the trigonometric equations (with the = equality symbol) and calculates the values of the unknowns.

All trig functions are supported: sin(), cos(), tan(), but also the trigonometry reciprocal functions acos(), arcsin(), and so on. as well as the hyperbolic functions cosh(), sinh(), etc.

Example: $\sin(x) = 0$ returns the solution $x = 0$ (radian)

Some equations will have an infinite number of solutions (modulo $\pi$ or $2\pi$ or with constants $c_i$)

All angles are in radian.

### How to solve multiple trigonometric equations?

Multiple trig equations with the same variables can be combined with a logical AND operator: && or .

Also, any new line return will be considered as a new equation.

### How to solve a trig equation step by step?

The dCode solver does not display the calculation steps because they do not reflect the steps of a human thinking but to the steps of a machine thinking (bit-by-bit binary calculation operations) far from a hand-held resolution. dCode allows you to check a result.
