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 ...

You’re standing at the edge of a cliff, phone in hand, trying to measure the distance to the opposite side – no tape measure, no drone, just your brain. Now what? Trigonometry just became your ...

An animated guide to using trigonometry. Trigonometric terms are explained and examples are used to show how to find unknown angles and sides for right-angled triangles. Use as an introduction or ...

Let’s look at how to use trigonometric identities to calculate missing sides. \({sin~θ} = \frac {opposite} {hypotenuse}\) \({cos~θ} = \frac {adjacent} {hypotenuse ...
