Online Trigonometry tutoring
Trigonometry is where many otherwise strong students hit a wall, almost always because the unit circle was introduced as something to memorise rather than something to understand and reconstruct.
01sin θ = opp / hyp02cos θ = adj / hyp03sin²θ + cos²θ = 104tan θ = sin θ / cos θ
Who it’s for
- Students in trigonometry or precalculus
- Students who memorised the unit circle and then lost it
- Students preparing for calculus
Topics covered
Right triangle trigonometry
The unit circle
Radian measure
Graphing sine and cosine
Trigonometric identities
Inverse trig functions
Law of sines and cosines
Common challenges
Where students usually get stuck.
The unit circle
Memorised values evaporate under exam pressure if the student can't rebuild them.
Identity selection
Students learn many identities but not which family of problems each one solves.
How tutoring helps
Our approach to Trigonometry.
Derive, don't memorise
Students who can reconstruct the unit circle never lose it before an exam.
Cumulative review
Ten minutes of each session revisits earlier material so nothing decays before finals.
