## How Does a Trig Exact Value Calculator Work?

The Trig Exact Value Calculator works by taking in the inputs and computing the exact trigonometric value of the angle. The Trig Exact Value Calculator works by using the following general formulas:

$\sin{\theta} = \frac{\text{Perpendicular}}{\text{Diagonal}}$

$\cos{\theta} = \frac{\text{Base}}{\text{Diagonal}}$

$\tan{\theta} = \frac{\text{Perpendicular}}{\text{Diagonal}}$

$\sec{\theta} = \frac{\text{Diagonal}}{\text{Base}}$

$\cot{\theta} = \frac{\text{Base}}{\text{Perpendicular}}$

## What Is Trigonometry?

Trigonometry is the study of the relationship between the ratios of the sides of a right-angled triangle and their angles. The trigonometric ratios used to examine this relationship are sine, cosine, tangent, cotangent, secant, and cosecant

Trigonometry is a 16th-century Latin derivative of the Greek mathematician Hipparchus’ notion.

Trigonometry fundamentals deal with angle measurement and angle-related difficulties. Trigonometry has three fundamental functions: sine, cosine, and tangent. Other essential trigonometric functions can be derived from these three fundamental ratios or functions: cotangent, secant, and cosecant. These functions are the foundation for all the vital ideas addressed in trigonometry.

## What Are Trigonometric Functions?

Trigonometric functions are complex numbers that can be calculated from the coordinates of a right triangle. The six primary Trig FUNCTIONs with domains as angles and answers ranging between -90° to 90°.

The domain of the trigonometric function (sometimes known as the ‘trig function’) of f(x) = sin is the angle represented in degrees or radians, and the range is [-1, 1]. Similarly, all other functions have domain and range. Calculus, geometry, and algebra all make heavy use of trigonometric functions.

The ratio of sides of a right-angled triangle is the basis for trigonometric functions and identities. The perpendicular side, hypotenuse, and base of a right triangle are used to determine the sine, cosine, tangent, secant, cosecant, and cotangent values using trigonometric formulas.
