How to use the trigonometry calculator

Steps to use the trigonometric function calculator: 1. Confirm input: select the correct mode (angle or radian) and enter the value. 2. Select function: Select the trigonometric function to be calculated (such as sine, cosine). 3. Input angle/radians: Enter the degrees or radians of the value to be calculated. 4. Get the result: Click the Calculate button to obtain the trigonometric function value. 5. Special values: Trigonometric functions at certain special angles have specific values ​​(such as sin(0°) = 0). 6. Advanced functions: Some calculators provide functions such as inverse trigonometric functions, hyperbolic trigonometric functions, and unit circle drawing.

How to use the trigonometric function calculator

1. Confirm input
Open After using the trigonometry calculator, first make sure the values ​​entered are correct. Most calculators provide two modes: angle and radian. You need to select the corresponding mode according to your needs.

2. Select function
Generally, the trigonometric function calculator supports six basic trigonometric functions: sine (sin), cosine (cos), tangent (tan), cotangent ( cot), secant (sec) and cosecant (csc). Select the function to calculate.

3. Enter the angle or radian
Enter the degree or radian value to calculate the trigonometric function value. Pay attention to whether the units entered are correct, for example, degrees are represented by degree symbols (°) and radians are represented by radians (rad).

4. Get the result
Click the "Calculate" or "Evaluate" button to get the trigonometric function value. Results are usually displayed in decimal form and may have multiple decimal places.

5. Special values ​​of trigonometric functions
For some special angles, trigonometric functions have specific values, for example:

• sin(0° ) = 0
• cos(0°) = 1
• tan(0°) = 0
• sin(30°) = 1/2
• cos(30°) = √3/2
• tan(30°) = √3/3

6. Advanced functions
Some advanced The trigonometric function calculator also provides the following functions:

• Inverse trigonometric functions (arcsin, arccos, arctan)
• Hyperbolic trigonometric functions (sinh, cosh, tanh)
• Trigonometric identity calculation
• Unit circle drawing
