How can I conceptualize sin, cos, and tan?
In: 1
Say you have a circle with radius 1 at the center of the 2D plane, and you start at the rightmost point of it. If you go around this circle counterclockwise by say 55°, then sin 55° is the y-coordinate of your destination, cos 55° is the x-coordinate of your destination, and tan 55° is the slope of the line that goes from the origin to your destination. Same for other angles.
