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 ...

Trigonometric graphs can be sketched when you know the amplitude, period, phase and maximum and minimum turning points. Working with trigonometric relationships in degrees Trigonometric functions can ...

Let's remind ourselves of what the sine graph looks like so that we can see how many solutions we should be expecting: Therefore, from the graph of the function, we can see that we should be expecting ...
