The unit circle is a circle centered at the origin with a radius of 1 unit. It is represented by the equation: x² + y² = 1

The values of x and y are determined using trigonometric functions: x = sin θ y = cos θ

Therefore, the values of sin θ and cos θ must be such that the sum of their squares equals 1.

The Slope (m): m = change in y / change in x

Equation of a straight line: y = mx
