📚Function Reference

Basic Trigonometric Functions

Function Description Formula
sin (Sine) Ratio of opposite side to hypotenuse opposite / hypotenuse
cos (Cosine) Ratio of adjacent side to hypotenuse adjacent / hypotenuse
tan (Tangent) Ratio of opposite side to adjacent opposite / adjacent = sin/cos
csc (Cosecant) Reciprocal of sine 1 / sin
sec (Secant) Reciprocal of cosine 1 / cos
cot (Cotangent) Reciprocal of tangent 1 / tan = cos/sin

Inverse Functions

Inverse trigonometric functions return the angle when given a ratio value. They are useful for solving triangles and converting between rectangular and polar coordinates.

Hyperbolic Functions

Hyperbolic functions are analogs of trigonometric functions but for hyperbolas instead of circles. They are commonly used in calculus, physics, and engineering applications.

💡Tips & Best Practices

💡 Pro Tip:

For angles in radians, remember that π (pi) ≈ 3.14159. Common angles: π/6 ≈ 0.524, π/4 ≈ 0.785, π/3 ≈ 1.047, π/2 ≈ 1.571

⚠️ Important:

Tangent, secant, cotangent, and cosecant functions are undefined at certain angles (like 90° for tan). The calculator will display "undefined" or "infinity" for these cases.

🎯 Accuracy:

For maximum precision in scientific work, use radians. Radian mode provides more accurate results for calculus and advanced mathematics applications.

🔄 Quick Conversions:

To convert degrees to radians: multiply by π/180. To convert radians to degrees: multiply by 180/π.
