If you need calculate sine, cosine, tangent or any other trigonometric ratio, here is a tool that will do it for you.
You simply select the function to be solved, enter the value, select whether you want the result in degrees or radians and finally, press the calculate button to obtain the result.
How our trigonometric calculator works
As you have already noticed, the operation of our trigonometry calculator is very simple. The first thing you have to do is to select the trigonometry function you want to use for the calculation.
All of them are available so you can choose between the following ones trigonometric functions:
When you have chosen the one you want to use, enter the number and select (if applicable) the unit as you may want to working in degrees or radians.
Finally, press the calculate button and you will get the result automatically. If the result should be an angle, the trigonometric calculator will give you the option to express it in degrees or in rads.
If you want to save yourself the calculations involved in each of the trigonometric ratios that we have exposed before, you can use the calculator that you have at the top of this post or use one of the tools dedicated exclusively to a specific function and to which we have left you a link.
Trigonometric ratios and their formulas
The following is a compilation of the main trigonometric ratios and how they are calculated from the sides of a right triangle. We leave you with the formulas for each function:
- Sine of Teta: opposite / hypotenuse
- Cosine of Tetaadjacent / hypotenuse
- Tangent of Tetaopposite / adjacent
- Arcoseno: 1 / breast
- Arcocoseno: 1 / cosine
- Arcotangent1/ tangent
- Cosecant of Tetahypotenuse / opposite
- Secant of Tetahypotenuse / adjacent
- Cotangent of Tetaadjacent / opposite
If you look closely, you will see that cosecant, secant and cotangent are the inverse of sine, cosine and tangent respectively.
It is important that you are very clear about how each function is obtained as this will is vital for solving math problems Trigonometry will always be with you from now on.
