Question

Can someone tell my what cos, sin and tan actually measure?

In: Mathematics

Answer 1

imagine a circle of radius 1. Now, make an angled line going from the center to the edge of that circle. The sin of the angle of that line is how high up the line goes, and cos is how far left/right the line goes. tangent is the slope of that line.
