Sine Calculator

Guide to Using the Sine Calculator

This step-by-step guide will walk you through the process of using the Sine Calculator to compute the sine of an angle and converting between degrees and radians.

Step 1: Input the Angle

• Look for the input field labeled Angle.
• Enter the desired angle value in this field. Ensure it is a number within the range of -360 to 360, as specified by the calculator’s validation requirements.
• Use increments of 0.1 degree or radian for precision.

Step 2: Select the Angle Unit

• Find the Angle Unit dropdown menu next to the angle input field.
• Choose between Degrees or Radians based on the unit of the angle you have entered.
• This selection is crucial because it dictates how the calculator will interpret your angle input for subsequent calculations.

Step 3: View the Result Fields

Once you have entered the angle and selected the appropriate unit, observe the result fields where various calculations are displayed:

• Sine Value: This field shows the sine of the provided angle, calculated using the formula:
  • If Degrees is selected, the calculator uses the formula sin(angle * π / 180).
  • If Radians is selected, it directly computes sin(angle).
• The sine value will be presented as a number formatted to six decimal places for precision.
• Angle in Radians: This field displays the angle converted into radians. If the original angle input was in degrees, it uses the conversion angle * π / 180. The result is rounded to six decimal places and labeled with a “rad” suffix.
• Angle in Degrees: This field provides the angle converted into degrees. If the angle was input in radians, it multiplies by 180 / π for the conversion. The value is formatted to two decimal places and is indicated with a “°” suffix.

Through these steps, you are able to effectively utilize the Sine Calculator for accurate trigonometric calculations and conversions. Ensure that all entries are correctly input according to the guidelines for precise results.
