Exact Value Of Trig Functions Calculator

Introduction: The Exact Value Of Trig Functions Calculator is a specialized tool for those working with trigonometry. It allows users to input an angle in degrees and quickly obtain the exact sine, cosine, and tangent values, ensuring precision in trigonometric calculations.

Formula: Trigonometric functions involve the calculation of ratios related to the sides of a right-angled triangle. The calculator utilizes standard trigonometric functions—sine, cosine, and tangent—to determine the exact values for a given angle in degrees.

How to use:

  1. Enter the angle (in degrees) in the provided text field.
  2. Click the “Calculate” button to obtain the exact sine, cosine, and tangent values.
  3. The results will be displayed in the “Exact Trig Values” input field.

Example: For instance, if you input an angle of 45 degrees and click “Calculate,” the calculator will provide the exact sine, cosine, and tangent values for a 45-degree angle.


  1. Q: Can I input angles greater than 90 degrees? A: Yes, the calculator provides exact values for any angle, including those greater than 90 degrees. Ensure you input the angle in degrees.
  2. Q: Are the results in decimal or fractional form? A: The results are provided in decimal form for simplicity. For fractional results, consider using specialized software or manual calculations.
  3. Q: Can I input negative angles? A: Yes, the calculator supports both positive and negative angles. Ensure you enter the angle in degrees.
  4. Q: Are the results rounded? A: Yes, the results are rounded to four decimal places for clarity. However, the underlying calculations are more precise.
  5. Q: Can I use this calculator for non-right-angled triangles? A: No, this calculator specifically calculates trigonometric values for right-angled triangles. For non-right-angled triangles, consider using other trigonometric methods.

Conclusion: The Exact Value Of Trig Functions Calculator simplifies trigonometric calculations by providing precise values for sine, cosine, and tangent based on a given angle in degrees. Whether you’re a student studying trigonometry or a professional requiring accurate results, this calculator is a valuable tool. For more advanced trigonometric calculations, users may explore specialized software or manual methods.
