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.
