How to use it
Type the problem as it is written, for example "solve 2 sin x - 1 = 0 for 0 ≤ x < 2π". Use ^ for powers and / for fractions.
Read the solution. It comes as numbered steps, each naming the rule it uses, and ends with the final answer.
If a step is unclear, ask about it in your own words, such as "explain step 2". Ask for a similar problem to try one yourself.
What trigonometry AI covers
- Trig ratios in right triangles (SOH-CAH-TOA)
- Exact values on the unit circle
- Simplifying expressions and proving identities
- Trig equations, with every solution in a given interval
- The laws of sines and cosines, for triangles the geometry solver also handles
- Inverse trig functions
- Amplitude, period and phase shift of a graph, worked out from its equation
Worked example: 2 sin x − 1 = 0 on [0, 2π)
Isolate the sine: sin x = 1/2.
On the unit circle, sine is 1/2 at x = π/6 in the first quadrant and at x = 5π/6 in the second.
So x = π/6 or x = 5π/6.
Common mistakes
- A calculator in degree mode when the problem uses radians, or the other way round.
- Giving one solution when the interval holds two or more.
- Reading sin²x as sin(x²). sin²x means (sin x)².
- Dividing both sides by sin x or cos x and losing the solutions where it is zero.
Questions students ask
Degrees or radians?
Say which one you want. If the problem doesn't say, the solver states the unit it uses.
Can it prove an identity?
Yes. It transforms one side into the other and names the identity used at each step. Identities come back in integrals, which calculus AI works through the same way.
Do I need an account?
No. You can type or dictate problems without signing in. Signing in with Google or Discord is free; it keeps your chats beyond 3 days and lets you attach a photo, PDF or Word file.
