In part 1 of this blog series, I shared a foolproof method for graphing transformed sine and cosine functions using the Eight Blanks method. I am going to show you how to extend this method to cover the other four trigonometric functions you typically encounter in Trig class: tangent, cotangent, secant, and cosecant. The base…

One of the big challenges my tutoring clients often face in Trigonometry class comes when they are asked to graph trigonometric functions with different amplitudes, periods, and shifts. Even when clients understand the basic principles, they often find it hard to keep track of and condense all the information they are given into one single…

Your Math class may have introduced you to a type of word problem called an optimization problem, sometimes referred to as a min / max problem. The objective of these is always the same: to find the maximum or minimum possible value of some quantity named in the problem. The weird thing about these problems…
