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.
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.
像真人导师一样进行的四个阶段
答案出现时，解题工具就完成任务；当你能独自解下一题，辅导才算完成。
给你方向，而不是直接给解答
它指出卡住的步骤，再把问题交回给你走出下一步。
逐行讲解，搭配图解
需要更多帮助时，它会逐行带你走过解法，而不只告诉你最终结果。
它会反过来问你一题
在继续之前，它会用一个简短问题确认下一步是否真正属于你。
稍后再回来复习
薄弱知识点会在更适合主动回忆、巩固解题方法的时机再次出现。
距离考试还有三周
导师会刻意放慢节奏，为下一题留下可重复使用的解题方法。
每学期最容易失分的三种习惯
Trigonometry punishes memorisation more than any other school level maths topic. These three are where the marks go.
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.
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.
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.
不是题库，而是从你的错误中生成的测验
Your marks are not lost evenly, so your practice is not spread evenly. Try this one.
这位导师涵盖的内容
From right triangle ratios through to the identities and equations that later courses assume are automatic.
Heading into calculus? Trigonometric derivatives and integrals assume all of this is automatic. Still building the algebra underneath?
Four things a maths tutor does that a chat box does not
它了解你的学习历程，不只是一道问题
下一次辅导会从你真正觉得困难的步骤开始，而不是泛泛地重讲整章内容。
它会画出图解，不只列出代数式
图解会带着标注与解题过程的每一步并列呈现，因为可视化推理本身也能得到分数。
它会找出你自己解题过程中的第一行错误
拍下做错的尝试，它会找到解法最早偏离的步骤，然后讲清这一步。
它按你的课程方式检验理解
长答题需要依照你自己试卷的格式练习，而不是套用选择题题库。
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.
学生真正会问的问题
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?
AskSia is built as a study aid, not an answer key. Check your own institution's policy before using any tool on graded work.
