Definition: Trigonometry equations

Trigonometry equations are mathematical expressions involving trigonometric functions such as sine, cosine, tangent, cosecant, secant, and cotangent.
Trigonometric equations can involve solving for unknown angles or side lengths, manipulating trigonometric identities, and applying trigonometric functions to real-world situations.

$1$

Explanation: The image is likely a trigonometric table. It lists the values of sine, cosine, tangent, and other trig functions for various angles in degrees and radians.

Definition: Unit circle

The unit circle is a circle with a radius of 1 unit, centered at the origin (0,0) on a Cartesian coordinate system. It’s used in mathematics, particularly in trigonometry, to represent the relationships between the angles and lengths of the sides of a right triangle.

$2$

Explanation: This image shows a circle with a radius of 1 unit. That’s a unit circle! It helps us connect angles with sine (sin) and cosine (cos), the basic functions in trigonometry.
