## INFORMATION

Sine is one of the most fundamental trigonometric functions. For a real angle between 0 and 90 degrees, the sine of the angle is the ratio of the length of the opposite side to the hypotenuse in a right triangle.

The above calculator computes the sine value of an angle given in degrees or radians. Additionally, it draws graphs representing the sine value of the angle. For angles between 0 and 90 degrees, it shows the sine value on a right triangle; for values between -3000 and +3000 degrees, it displays the sine value on the coordinate system; and for all angles, it represents the sine value on the unit circle.

## INPUT FORMAT

Available input formats are listed below.

• Integers (e.g., 3 or 27)
• Decimal numbers (e.g., 27.5 or 0.05)
• Fractions (e.g., 1/2 or 2.3/4)

### WHAT IS SINE CALCULATOR?

Sine calculator,

• Computes the sine of an angle given in degrees or radians and
• Illustrates the angle and its sine value on different graphs.

### HOW TO USE THE SINE CALCULATOR?

Sine calculator can be used in two ways.

• #### USER INPUTS

You can enter the angle value to the input box and click on the "CALCULATE" button. The result and explanations appaer below the calculator.

• #### RANDOM INPUTS

You can click on the DIE ICON next to the input box. If you use this property, a random angle value is generated and entered to the calculator, automatically. The result and explanations appaer below the calculator. You can create your own examples and practice using this property.

• #### SELECTING THE UNIT

You can select the unit of the angle by clicking on the selection box next to the input.

• #### CLEARING THE INPUT BOX

To find sine value of some other angles, you can clear the input box by clicking on the CLEAR button.

• You can copy the generated solution by clicking on the "Copy Text" link, appaers under the solution panel.
