# Trig Exact Value Calculator

Result:

The Trig Exact Value Calculator is a simple tool designed to compute the exact values of trigonometric functions (sine, cosine, and tangent) for a given angle in degrees. It is particularly useful for students and professionals working with trigonometry.

Formula: Trigonometric functions are calculated using the angle in degrees and standard mathematical functions. The exact formulas are as follows:

• Sine (sin): sin(angle)
• Cosine (cos): cos(angle)
• Tangent (tan): tan(angle)

How to Use:

1. Enter the angle in degrees in the provided input field.
2. Select the desired trigonometric function from the dropdown menu.
3. Click the “Calculate” button to obtain the exact value.

Example: Suppose you want to find the sine value for an angle of 30 degrees. Enter 30 in the angle input field, choose “Sine” from the dropdown, and click “Calculate.” The result will be displayed.

FAQs:

1. Q: Can I enter negative angles? A: Yes, you can enter negative angles. The calculator handles both positive and negative values.
2. Q: What happens if I choose an invalid function? A: If an invalid function is selected, the calculator will display “Invalid function.”
3. Q: Is the calculator limited to a specific range of angles? A: No, the calculator can handle angles of any value, positive or negative.
4. Q: How does the calculator handle non-numeric input? A: The calculator requires numeric input for the angle. Non-numeric input will prompt an error.
5. Q: Can I use this calculator for radians instead of degrees? A: No, this calculator specifically operates with angles in degrees.

Conclusion: The Trig Exact Value Calculator simplifies the process of finding exact values for trigonometric functions, providing quick and accurate results for various angles. Whether you’re a student studying trigonometry or a professional in need of precise calculations, this calculator is a valuable tool.
