Trigonometry Tutor Online: 1-to-1 Help

How it works, in short

Trigonometry tutoring at TaleemSquare is one-to-one and 45 minutes per lesson. Tutors start wherever your child is, from first right-triangle ratios in Grade 9 or 10 to the unit circle, radians, graphs, identities and trig equations in Algebra 2, precalculus or senior courses.

Trig builds in layers, so a weak first layer causes problems for years. The free assessment shows which layer needs work. Plans start at $85 a month.

What changes after a term of lessons

Lessons happen on a shared whiteboard, so your child solves while the tutor watches and guides (example lesson).

Picks the right ratio every time

Labels opposite, adjacent and hypotenuse correctly and knows when to use sine, cosine, tangent or their inverses.

Knows the unit circle

Finds exact values in degrees and radians and understands where each value comes from.

Solves non-right triangles

Uses the laws of sines and cosines and the area formula, including tricky ambiguous cases.

What we cover

Lessons follow your child's own school or homeschool curriculum. These are the areas we work on most at this level.

Right-triangle trigonometry

SOH CAH TOA, inverse trig to find angles, angles of elevation and depression, and bearings.

Special triangles and exact values

30-60-90 and 45-45-90 triangles and the exact values that come from them.

Laws of sines and cosines

Solving any triangle, the ambiguous case and the sine area formula.

Radians and the unit circle

Converting between degrees and radians, reference angles and signs in each quadrant.

Trig graphs

Graphing sine, cosine and tangent with changes in amplitude, period and phase.

Identities and equations

Pythagorean and double-angle identities, proving identities and solving equations over an interval.

Signs your child could use help

Mixes up opposite and adjacent sides
Calculator gives wrong answers because of degree and radian mode
Can't remember exact values without a chart
Bearings and elevation questions cause panic
Identity proofs go in circles
Trig is pulling down an otherwise good grade

One of these on its own is normal. Two or three together usually point to a specific gap, and finding it is what the free assessment is for.

Taught to your curriculum, wherever you live

Geometry, Algebra 2 and Precalculus (state standards)

Right-triangle trig usually appears in Geometry, the unit circle and trig functions in Algebra 2 or Precalculus. Some schools offer a standalone Trigonometry course. We follow whichever course your child is in.

GCSE Maths and A-level Mathematics

GCSE covers SOH CAH TOA and exact values, with the sine and cosine rules on the Higher tier. A-level adds radians, identities and trig equations. We follow your exam board.

Level: GCSE trigonometry to A-level

Provincial Grades 10-12 mathematics

Trigonometry is taught in Grade 10 math and developed in Grade 11-12 functions courses such as Ontario's MCR3U and MHF4U. We follow your province's course.

Level: Grades 10-12 trigonometry

Australian Curriculum and senior mathematics

Years 9 and 10 cover right-triangle trig and the sine and cosine rules. Senior Methods, Advanced and Specialist courses add the unit circle, radians and trig functions.

Level: Years 9-12 trigonometry

How we teach trigonometry

Label before you calculate

Every triangle gets labeled from the angle's point of view before any ratio is chosen. This one habit removes most errors.

Build exact values from triangles

Students derive the unit circle values from two special triangles, so they can rebuild them in an exam.

Check the calculator

We make degree and radian mode a checklist item, because it causes a surprising number of lost marks.

Real contexts

Heights, ramps, navigation and waves make trig concrete and match the word problems schools set.

Fractions and multiplication practice worksheet — Practice set for between lessons (example).

Student progress report showing math skills — Progress by skill, reviewed with you (example).

WhatsApp message from a math tutor to a parent — A WhatsApp update after every class (example).

Full pricing and how we compare

Common worries, honest answers

“My child just needs help with one trig unit.”

That is fine. Many families use us for a specific unit, then pause. You can cancel any month without a contract.

“Will online lessons work for drawing triangles?”

Yes. Your child draws on the shared whiteboard with a mouse, trackpad or tablet stylus, and the tutor can annotate the same diagram.

“My child is good at memorizing but forgets everything later.”

We teach where formulas come from, which makes them far easier to recall months later in exams.

Frequently asked questions

What grade is trigonometry taught in?

In the US, right-triangle trigonometry is usually introduced in Geometry (Grade 9 or 10). The unit circle and trig functions come in Algebra 2 or Precalculus (Grades 10-12). In England, trigonometry starts in GCSE Maths, and in Australia it begins in Year 9 or 10.

What is SOH CAH TOA?

SOH CAH TOA is a memory aid for the three main trig ratios in a right triangle: sine equals opposite over hypotenuse, cosine equals adjacent over hypotenuse, and tangent equals opposite over adjacent. The hard part for most students is labeling the sides correctly relative to the angle.

How do I memorize the unit circle?

It is easier to understand than to memorize. The values come from two special triangles, 30-60-90 and 45-45-90, reflected into each quadrant. Once a student can rebuild it from those triangles, they rarely forget it.

How much does an online trigonometry tutor cost?

At TaleemSquare, one-to-one trigonometry tutoring starts at $85 a month for two 45-minute lessons a week, which is about $10.63 a lesson. Three lessons a week is $119 and four is $149, with no contract, no registration fee and a free first assessment. Private trigonometry tutors in the US often charge $40-$60 an hour or more.

Can a tutor help with trig identities?

Yes. Identity proofs follow a handful of strategies, such as rewriting in sine and cosine, finding a common denominator or using a Pythagorean identity. Tutors teach these strategies and practise choosing between them.

Is trigonometry on the SAT?

Yes, a small number of digital SAT Math questions cover right-triangle trigonometry and related geometry, including sine, cosine and tangent. Strong trig basics help on those questions.
