What is Circular Functions Graph Calculator?

A circular functions graph calculator is an online tool used to evaluate the six trigonometric functions (sine, cosine, tangent, cotangent, secant, and cosecant) for a given angle. It helps students, educators, and professionals quickly find the values of these functions without manual calculations. The calculator understands that trigonometric functions are periodic and repeat their values at regular intervals, which is why they are called circular functions.

Circular Functions Graph Calculator Formula and Explanation

The calculator uses the following formulas:

\n
• Sine: sin(θ) = y/r
\n
• Cosine: cos(θ) = x/r
\n
• Tangent: tan(θ) = y/x
\n
• Cotangent: cot(θ) = x/y
\n
• Secant: sec(θ) = r/x
\n
• Cosecant: csc(θ) = r/y
\n

Where θ is the angle in degrees, x and y are the coordinates of a point on the unit circle, and r is the radius (distance from the origin to the point). The calculator automatically converts the input angle from degrees to radians using the formula: radians = degrees × (π/180).
