Trigonometry Calculator

Trigonometry Calculator

The Trigonometry calculator is used to determine the trigonometric functions of the input parameters. The first step of using the calculator is to select the trigonometric function. Some of them include Sin, Cos, Tan, Csc, Sec and many others. The next text field is where you will enter the input parameter. Choose the angle type and then click the ‘Calculate’ button. It is used to execute the conversions of the values and selected options in the respective text fields. The results will be displayed in the bottom platform of the calculator. The “X” button is used to reset the calculator when you want to perform new calculations.

Example 1

What is the sin of 45°?

Solution

Select the ‘Sin’ option and enter 45 in the blank text field and select degrees as the angle type. Click the ‘Calculate’ button to initiate the conversion.

The result will be displayed as; 0.70710678

The results in radians would be displayed as; 0.85090352

Example 2

What is the Cos of 60°?

Solution

Select the ‘Sin’ option and enter 60 in the blank text field and select degrees as the angle type. Click the ‘Calculate’ button to perform the calculation

The result will be displayed as; 0.8660254

If the angle type was in radians, the result would be; -0.30481062

If you want to perform new calculations or choose a different trigonometric function, you will use the ‘X’ button to erase all the previous data from the text fields. The Trigonometry calculator uses particular formulas in performing the calculations.

The Trigonometric Functions

Tan A = Opposite / Adjacent = a/b

Cos A = Adjacent / hypotenuse = b/c

Sin A = Opposite / adjacent = a/c

Cot A = Adjacent / opposite = b/a

Csc A = Hypotenuse / opposite =c/a

Sec A = Hypotenuse / adjacent =c/b
