anyway /sci/ can explain wtf sin cos and tan mean? I understand what it is but I don't understand how it works intuitively. I can't find anything regarding the intuitive side of it on YouTube.

Like the other guy said, they're ratios.

Take a cartesian plane, draw a circle around the origin with radius 1. Draw any line from the origin to a point on the circumference; suppose this line makes an angle G with the positive x-axis. Then the horizontal component of the line is cos G and the vertical is sin G. IN other words, the point on the circle it intersects is (cosG, sinG).


Draw a unit circle yourself and convince yourself of this

Mathematical intuition is not something one is born with,
it is developed over the course of years of study and practice.
