Now let us start with the basic formulas of trigonometry and see the basic relationships on which the whole concept is based on.

In a right-angled triangle, we have Hypotenuse, Base and Perpendicular.

I use Scientific Notebook or similar math software to graph the functions for me.

You can use this Online Graphing Calculator to solve the following equations (or check your solutions) .

Going back, just remember there are infinitely many solutions, two per period and the two solutions in a given period are related in that they are the supplements of one another.

## Solving Trigonometric Problems

We get one solution by using inverse sine, we get another solution by using the fact that the sine of a supplement is the same as the sine of the angle and finally use periodicity to get the remaining solutions.

But a great many can be solved in closed form, and this page shows you how to do it in five steps.

Bourne Trigonometric equations can be solved using the algebraic methods and trigonometric identities and values discussed in earlier sections.

Now to get started let us start with noting the difference between Trigonometric identities and Trigonometric Ratios.
