This all started with a student my wife was helping with high school trigonometry homework. Here is one of the questions. Here is the solution that the homework was looking for: This uses the ...

Description: 👉 Learn how to graph a cosine function. To graph a cosine function, we first determine the amplitude (the maximum point on the graph), the period (the distance/time for a complete ...

Description: 👉 Learn how to graph a secant function. To graph a secant function, we start with the cosine graph by first determining the amplitude (the maximum point on the graph), the period (the ...

A complete lesson on the graphs of sine and cosine from 0 to 360 degrees. I’ve also made complete lessons on tangent from 0 to 360 degrees and all three functions outside the range 0 to 360 degrees.

Trigonometric identities are powerful tools for simplifying complex equations in math and science. Three core groups—reciprocal, quotient, and Pythagorean—form the foundation. Effective strategies ...

Interactive macro-enabled MS-Excel spreadsheet. Contents: Complete a table & draw the unit circle using cos θ (x) & sin θ (y). Complete a table & draw the tangent to the unit circle using tan θ.

I am have a slight problem with two recursive functions I wrote: Sine and Cosine. Each function depends on the other (and itself) to compute the value of Sine and Cosine for any value input. I am ...
