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.

Trigcalc does contain ads but only shows them after a sum of calculations.
These ads can be removed for a one time fee of $5.99.

Love this app! 💜

Words can not explain the LOVE I have for this app! It’s helped me countless amount of times with work I had a hard time understanding. If you have issues or problem with your class/work then this app is a must! On top of that the app feels very clean with no bugs and a aesthetically pleasing UI

I literally cannot express how much I love this app, I’ve never written a review ever about any app ever and this one literally is so helpful that I just had to. Amazing app, thank you to the creators of it.

Very easy to use

Great app. Incredibly simple and easy to use. Highly recommend having this app even if you’re not in Trigonometry. These types of problems are given in other classes too and this can come in handy a lot.
