About Algebra Tutorial 9
In this tutorial, we look at the domain and range of the inverse of a function.
We then see that we can convert a non-invertible function into an invertible function by restricting its domain.
Finally, we use a domain restriction for each of the trigonometric functions sine, cosine and tangent to make them invertible, and we use these inverse trigonometric functions to solve trigonometric equations.
* Aimed at students in their final two years of high school.
* Studying mathematics is best done by working through examples and exercises. There are many interactive examples and exercises in this tutorial that must be completed to achieve 100% progress.
* Written by a Maths teacher with 20 years of teaching experience.
* Completely free (no Ads).
* Works without internet so that you can learn Algebra while travelling in the train, bus etc. Internet only required for links to privacy policy and other tutorials.
* Made with GameMaker.
