Sin Cos Tan Calculator with Square Root

This calculator provides accurate trigonometric functions (sine, cosine, tangent) along with square root calculations. It's perfect for students, engineers, and anyone needing precise trigonometric values with square root functionality.

How to Use This Calculator

Using the sin cos tan calculator with square root is straightforward:

Enter your angle value in the input field
Select the angle unit (degrees or radians)
Choose which trigonometric functions to calculate (sin, cos, tan)
Check the "Include square root" option if needed
Click "Calculate" to get results

The calculator will display the results in the result panel below. You can also view a chart visualization of the trigonometric functions.

Formulas Used

The calculator uses standard trigonometric formulas:

Trigonometric Functions

sin(θ) - Sine of angle θ

cos(θ) - Cosine of angle θ

tan(θ) - Tangent of angle θ (tan(θ) = sin(θ)/cos(θ))

Square Root

√x - Square root of x (√x = x^(1/2))

All calculations are performed using JavaScript's built-in Math functions for maximum accuracy.

Worked Examples

Example 1: Basic Trigonometric Calculation

Calculate sin, cos, and tan of 30 degrees:

Function	Value
sin(30°)	0.5
cos(30°)	0.866
tan(30°)	0.577

Example 2: With Square Root

Calculate √(sin²(45°) + cos²(45°)):

sin(45°) ≈ 0.7071

cos(45°) ≈ 0.7071

sin²(45°) + cos²(45°) ≈ 0.5 + 0.5 = 1

√(1) = 1

Interpreting Results

The calculator provides precise values for trigonometric functions. Here's what each result means:

Sine - Represents the ratio of the length of the opposite side to the hypotenuse in a right triangle
Cosine - Represents the ratio of the length of the adjacent side to the hypotenuse
Tangent - Represents the ratio of sine to cosine (opposite/adjacent)

Note: For angles where cosine is zero (90° in degrees or π/2 in radians), the tangent function is undefined.
