Trigcalc aims to make trigonometry calculations as simple yet detailed as possible. Trigcalc provides step-by-step solutions to some of the most common trigonometry and geometry problems. Trigcalc also uses real math notation such as radicals, exponents, fractions, pi, and more. The list of supported calculators are shown below:

- Right Triangles
- Oblique Triangles (non-right triangles)
- Circles
- Sectors
- Trigonometric Identities
- Coterminal Angles
- Supplementary Angles
- Complementary Angles
- Trigonometric Functions
(and growing)

For right triangle calculations, only two values are required so long as one of them is a side length. About two seconds after submitting a calculation a solution is returned which includes the exact values of all sides, angles, the area, the perimeter, and step-by-step explanations for each value. This same calculation and solution process is used for all Trigcalc calculations.
