Personal AI Trigonometry Tutor Online That Teaches the Method

Ask about an identity and the tutor asks you to place the angle on the unit circle first, because almost every trigonometry formula is readable off that diagram and almost none of them survive as a memorised list.

Quick answer

What is the AskSia AI trigonometry tutor?

The AskSia AI trigonometry tutor is a personal tutoring tool that derives identities from the unit circle rather than presenting them as a formula sheet. It hints at where the angle sits, walks the derivation when you ask, and puts a related angle back to you at the end. It covers right triangle ratios, the unit circle, radians, graphs and transformations, identities, equations, inverse functions and the sine and cosine rules. It answers in eight languages. Students on the AskSia A+ plan are covered by the Grade Confidence Guarantee. AskSia is a study aid, not an answer key.

How a session runs

Four stages, the way a tutor actually works

A solver ends when the answer appears. Tutoring ends when you can do the next one alone.

1
Hint

A nudge, not a solution

It points at the broken step and hands the problem back for your next move.

2
Walkthrough

Line by line, with the picture

Ask for more and it works through the method line by line, not just the final result.

3
Checkpoint

It asks you one back

A short question makes sure the next step belongs to you before you move on.

4
Quiz

It comes back later

Weak topics return later, when retrieval is more likely to make the method stick.

You need the answer now

It is 11pm and the set is due

Use the solver for a complete worked solution when the deadline is the priority.

You need to be able to do it

The exam is in three weeks

The tutor is slower on purpose, because it leaves a method behind for the next problem.

Where the marks go

Three habits that cost marks every semester

Trigonometry punishes memorisation more than any other school level maths topic. These three are where the marks go.

01

Treating identities as a list to memorise

A memorised sheet fails the moment the question needs a rearranged version. The tutor derives each identity from the unit circle so you can rebuild it under pressure.

02

Losing solutions when solving equations

Dividing both sides by a trigonometric term deletes valid solutions silently. The tutor asks whether that term could be zero before any division.

03

Ignoring the ambiguous case in the sine rule

Two triangles can satisfy the same data, and answering with one loses the question. The tutor asks whether the given angle is opposite the longer side.

Practice and tracking

Quizzes built from your mistakes, not a question bank

Your marks are not lost evenly, so your practice is not spread evenly. Try this one.

From your weak topicsSOLVING EQUATIONS
Solving sin 2x equals sin x, a student divides both sides by sin x. What goes wrong?
Why this answer. Why B. Dividing by an expression assumes it is not zero, so every solution where sin x equals zero disappears from the answer. Factorising instead of dividing keeps them, which is why the tutor asks whether the term you are cancelling could be zero.
Long-response questions are graded on the reasoning in each step, not only the final value.

Tutoring, not a chat box

Four things a maths tutor does that a chat box does not

It knows your history, not just your question

Your next session starts with the steps that have actually been difficult, not a generic recap of the whole topic again.

It draws the diagram, not just the algebra

Diagrams are labelled and built beside every step of the working, because visual reasoning can earn marks in its own right.

It finds the first wrong line in your own working

Bring an attempt that went wrong. It finds the first step where the method changed course, then teaches that step.

It examines you the way your course does

Long-response questions need practice shaped like your own paper, not a multiple-choice bank.

Why this works

Why the formula sheet is the problem

Students who memorise identities can reproduce them and cannot rearrange them, which is what exam questions actually require. The tutor derives each one from the unit circle, so the sheet becomes something you can rebuild rather than something you can lose.

Personal here means it remembers which move keeps failing. If your identities are solid but you lose roots whenever you divide, that is tracked separately and practice returns to it.

It tutors in English, German, Japanese, Korean, Spanish, Portuguese, Simplified Chinese and Traditional Chinese.

Questions

Questions students actually ask

Does it just give me the identity?

No. It asks where the angle sits on the unit circle and derives the identity with you. Each walkthrough ends with a related angle put back to you. You can request the formula at any point, but it will not lead with it.

Can it help me stop losing solutions?

Yes, and this is the most requested topic. The habit it teaches is to factorise rather than divide, and it checks that habit in your own working.

Does it cover radians properly?

Yes, including why later courses use them exclusively, which makes the conversion feel less arbitrary.

Can I photograph handwritten working?

Yes, including crossings out, and it marks the earliest line where the working broke.

Does it cover the ambiguous case?

Yes. It asks about the relationship between the given angle and the sides before any rule is applied, which is what surfaces the second triangle.

Is using an AI trigonometry tutor allowed?
