## Trigonometric functions

sin *A* = opposite / hypotenuse = *a* / *c*

cos *A* = adjacent / hypotenuse = *b* / *c*

tan *A* = opposite / adjacent = *a* / *b*

csc *A* = hypotenuse / opposite = *c* / *a*

sec *A* = hypotenuse / adjacent = *c* / *b*

cot *A* = adjacent / opposite = *b* / *a*

Here we discuss list of online math calculators that help us for doing calculation easily.

### Trigonometry Calculator

Trigonometry Calculator is a free online tool that displays the values of six important trigonometric functions. Online trigonometry calculator tool makes the calculation faster, and it displays the trigonometric values in a fraction of seconds. Trigonometry calculator can support you in finding the trigonometric functions values or solving the right triangle.

Trigonometric functions

sin A = opposite / hypotenuse = a / c

cos A = adjacent / hypotenuse = b / c

tan A = opposite / adjacent = a / b

csc A = hypotenuse / opposite = c / a

sec A = hypotenuse / adjacent = c / b

cot A = adjacent / opposite = b / a

** How to Use the Trigonometry Calculator?**

The procedure to use the trigonometry calculator is as follows:

1. Enter the value of the base and perpendicular side in the respective input field

2. Now click the button “Calculate” to get the trigonometric value

3. Finally, the value of six trigonometric functions will be displayed in the output field

** What is Meant by Trigonometry?**

In Maths, trigonometry is a branch that deals with the sides and the measure of the angle for the right angle triangle. The trigonometric function is also known as the circular function. Based on the angles and the sides, the trigonometric functions are classified into six important types. They are Sine, Cosine, Tangent, Cosecant, Secant, and Cotangent. The ratio to define these function are given below:

Sin Function = Opposite Side/Hypotenuse

Cos Function = Adjacent/ Hypotenuse

Tan Function = Opposite Side / Adjacent Side

Cosec Function = Hypotenuse / Opposite Side

Sec Function = Hypotenuse / Adjacent Side

Cot Function = Adjacent Side / Opposite Side

** Trigonometry calculator finding sin, cos, tan, cot, sec, csc**

To find the trigonometric functions of an angle, enter the chosen angle in degrees or radians. Underneath the calculator, six most popular trig functions will appear - three basic ones: sine, cosine and tangent, and their reciprocals: cosecant, secant and cotangent. Additionally, if the angle is acute, the right triangle will be displayed, which can help you in understanding how the functions may be interpreted.

** Trigonometry calculator as a tool for solving right triangle: **

To find the missing sides or angles of the right triangle, all you need to do is enter the known variables into the trigonometry calculator. You need only two given values in the case of:

1. one side and one angle

2. two sides

3. area and one side

Remember that if you know two angles, it's not enough to find the sides of the triangle. Two triangles having the same shape (which means they have equal angles) may be of different sizes (not the same side length) - that kind of relationship is called triangle similarity. If the sides have the same length, then the triangles are congruent.
