Trigonometry Calculator Explained – Formulas, Angles & Ratios
The **Trigonometry Calculator** helps you find the trigonometric ratios for any angle. It supports sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc) values. You can easily switch between **degrees and radians** and get accurate trigonometric results instantly.
Trigonometric Ratios and Their Formulas
- sin(θ) = Opposite / Hypotenuse
- cos(θ) = Adjacent / Hypotenuse
- tan(θ) = Opposite / Adjacent
- cot(θ) = 1 / tan(θ)
- sec(θ) = 1 / cos(θ)
- csc(θ) = 1 / sin(θ)
Inverse Trigonometric Functions
- sin⁻¹(x), cos⁻¹(x), tan⁻¹(x) return angles for known ratios.
- Used to find unknown angles in triangles.
Unit Circle Basics
The **unit circle** (radius = 1) is a key visualization in trigonometry. It helps understand how sine and cosine correspond to y and x coordinates of a circle at any angle.
Applications of Trigonometry
- Architecture, navigation, and astronomy.
- Physics and engineering (wave motion, angles, distances).
- Computer graphics and 3D modeling.
Tips for Accurate Trig Calculations
- Always confirm whether your input is in degrees or radians.
- Be cautious with tangent and cotangent — they’re undefined at certain angles.
- Round to 3–6 decimal places for best precision.
FAQs
Q: What’s the difference between degrees and radians?
A: Degrees divide a circle into 360 parts, while radians use π as the base (1 circle = 2π radians).
Q: Can this calculator find missing triangle sides?
A: Yes, use the trigonometric ratios based on known sides and angles.
