Calculator UseThis online trigonometry calculator will calculate the sine, cosine, tangent, cotangent, secant and cosecant of angle values entered in degrees or radians. The trigonometric functions are also known as the circular functions. To calculate these functions in terms of π radians use Trigonometric Functions Calculator ƒ(π). Show

Enter the Angle: ∘ Sine ∘ = Trig Function Calculator is a free online tool that displays the values of six important trigonometric functions. BYJU’S online trig function calculator tool makes the calculation faster and it displays the trigonometric function values in a fraction of seconds. How to Use the Trig Function Calculator?The procedure to use the trig function calculator is as follows: Step 1: Enter the angle in the input field Step 2: Now click the button “Calculate” to get the trigonometric function values Step 3: Finally, the trig function values will be displayed in the output field What is Meant by Trig Function?In mathematics, trigonometry is a branch that deals with the study of angles and sides of a right triangle. Based on the sides and the angles, the trigonometric functions can be classified into six types, namely sine, cosine, tangent, cosecant, secant and cotangent. The trigonometric ratios of these six functions are given below Sine Function = Opposite Side / Hypotenuse Cosine Function = Adjacent Side/ Hypotenuse Tangent Function = Opposite Side/Adjacent Side Cosecant Function = Hypotenuse/Opposite Side Secant Function = Hypotenuse / Adjacent Side Cotangent Function = Adjacent Side/ Opposite Side On this page is a trigonometric functions calculator, which calculates the result for a given input angle for the 6 trigonometric functions – sine, cosine, tangent, cotangent, secant, and cosecant. Trigonometry Functions CalculatorUsing the Trigonometric Functions CalculatorTo use the tool to find the results of the trigonometric functions for a given angle, enter the angle, choose how its measured (degrees or radians) and compute.
Where results are undefined, you'll see "NaN". What are the trigonometric functions?The trigonometric functions, which are defined in terms of the unit circle – or, for angles under 90 degrees (square), alternatively defined using a right triangle. Right Triangle Diagram (CC By-SA 3.0 Wikimedia)In terms of the right triangle, the functions are defined as:
If you know the result of one of the trigonometric functions already, you can reverse it into an angle using the inverse trigonometry functions calculator. Trigonometric FunctionsWe've built tools for computing both the trigonometric functions and their inverses. Find them here: Which calculator is best for trigonometry?Texas Instruments TI-84 Plus CE
