Pre-calculus

Understanding Trigonometric graphs 

In order to fully appreciate the behavior of functions, 

often we need to graph them, Trigonometric 

identities and functions are primal in the methods of

calculus. The functions are also useful to appreciate 

the areas of Physics and chemistry like Acoustics and

Quantum physics, Coordinate geometry, Computer


graphics, Computer Aided Design, Vector calculus so 

on.

In this web lecture we will try my patented  

WWW "What if ? Why? Why not?" 

approach to graphing these functions.



The red-black picture on top is a 3 Dimensional graph

 of Tan x function, each outward radiating spoke is a 

asymptote of Tan approaching outwards(towards the 

screen in 3 Dimension) limiting towards infinity.
