I'm currently learning the unit circle definition of trigonometry. I have seen a graphical representation of all the trig functions at khan academy.
I understand how to calculate all the trig functions and what they represent. Graphically, I only understand why sin and cos is drawn the way it is. I'm having trouble understand why tangent, cotangent, secant, cosecant are drawn the way they are.
Can someone please provide me with some intuitions.
