How to Use the Tan Calculator

This guide will walk you through the process of using the Tan Calculator to find the tangent of an angle, as well as the sine, cosine, and the angle in radians. The calculator uses degrees for input and allows you to specify the precision of the result.

Step 1: Enter the Angle

Angle (in degrees):
Begin by finding the input field labeled “Angle (in degrees).” You need to enter the angle for which you want to calculate the tangent. Make sure the angle is in the valid range of -89.999 to 89.999 degrees to avoid undefined values. Use the number input field to type in your desired angle.

Step 2: Select Decimal Precision

Decimal Places:
Locate the second input field labeled “Decimal Places,” which is a dropdown menu. From this menu, select the desired number of decimal places for your results. The options available are 2, 4, 6, or 8 decimal places. Choose the level of precision that meets your needs.

Step 3: Calculate Results

Once you’ve entered the angle and selected the precision, proceed to calculate the results. The calculator will compute the following values:

  • Tangent Value: The tangent of the angle is calculated using the formula tan(angle * pi / 180) and displayed with your selected decimal precision.
  • Opposite Length: This field shows the sine of the angle, represented by sin(angle * pi / 180), formatted to the chosen decimal places.
  • Adjacent Length: The cosine value of the angle, given by cos(angle * pi / 180), is also provided.
  • Angle in Radians: Finally, the angle converted into radians is calculated with angle * pi / 180 and formatted accordingly.

All the calculations are automatically performed once you provide the inputs and each result is accurately displayed with the chosen formatting.

Step 4: Review Your Results

Carefully review the displayed results. Ensure that the angle and precision chosen were correctly entered. The tangent, sine, cosine, and radian values should correspond to the angle input.

By following these simple steps, you can efficiently use the Tan Calculator to determine trigonometric values with ease and precision.
