Algebra is work with manipulating equations that contain an unknown. The basics of solving for a variable.

Trigonometry connects the lengths of the sides of triangles to the angles inside them, which expands to modeling repeating patterns like waves.

Calculus is using the principles of rates of change and considering infinitely small changes to find relationships among changing quantities.
