👉 Learn the basics to graphing sine and cosine functions. The sine graph is a sinusoidal graph with x-intercepts at x = 2n*pi, maximum value of 1 at x = pi/2 + 2n*pi, and minimum value of -1 at x = ...

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 ...

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

Being able to identify which formula to use, sine or cosine, and when, is necessary to answer questions on this topic successfully. Check you are confident in how to use the sine and cosine rules.

Excel has built-in functions for sine and cosine, the two core trigonometric functions, and for hyperbolic sine and hyperbolic cosine, their hyperbolic counterparts. It also has built-in functions for ...
