What we cover in Precalculus
Precalculus is usually grade 11, or grade 10 on an advanced track. Every topic of the course, taught 1-on-1 at your pace and in your class's order.
- Functions, transformations and inverses
- Polynomial and rational functions
- Exponential and logarithmic functions and models
- Trigonometric functions and the unit circle
- Trig identities and equations
- Polar coordinates and complex numbers
- Vectors and parametric equations
- Sequences, series and an introduction to limits
- AP Precalculus units 1 to 3, for the May exam
How we plan your Precalculus classes
Adapted after your free demo class: we spend the time where it matters most for you.
- Find the gapsYour free demo class starts with a few questions to see which earlier skills are solid and which need work.
- Fix the foundationsWe fill those gaps first, because most trouble in Precalculus comes from a skill from an earlier course.
- Keep ahead of classEach week we work on your homework and the next topic your teacher will cover, so class makes sense the first time.
- Prepare for testsUnit tests and finals, and the AP Precalculus exam in May for AP students, with timed practice and an error log.
Try two Precalculus questions
Typical class-test questions. Have a go, then open the worked solution.
Precalculus · question 1
Solve 2 sin θ − 1 = 0 for 0 ≤ θ < 2π.
Show the worked solution
- Rearrange: sin θ = 1/2.
- On the unit circle, sine is 1/2 in quadrant I at π/6.
- Sine is also positive in quadrant II: π − π/6 = 5π/6.
- Answer: θ = π/6 or 5π/6.
Precalculus · question 2
For f(x) = (x² − 4) / (x² − x − 2), find the hole, the vertical asymptote and the horizontal asymptote.
Show the worked solution
- Factor: f(x) = (x − 2)(x + 2) / ((x − 2)(x + 1)).
- x − 2 cancels, so there is a hole at x = 2, where the simplified function gives (2 + 2)/(2 + 1) = 4/3.
- The remaining denominator is zero at x = −1: a vertical asymptote.
- The degrees match, so the horizontal asymptote is the ratio of leading coefficients, 1/1.
- Answer: Hole at (2, 4/3), vertical asymptote x = −1, horizontal asymptote y = 1.
Where Precalculus leads
Each course builds on the one before, so a strong Precalculus makes the next class easier.
Algebra 1 → Geometry → Algebra 2 → Precalculus → AP Calculus AB or BC
AP Physics 1 also uses algebra and trigonometry from these courses on almost every question.

What families say
“Studying with Ashraf has been a game-changer for my son’s mathematical journey. Over the past year, Ashraf’s guidance has helped him approach problems with clarity, confidence, and creativity. His teaching goes beyond formulas, nurturing logical thinking and strategic problem-solving. This approach directly reflected in my son’s competition performance: after earning a Silver medal in HKIMO last year, he proudly achieved Gold this year. Ashraf’s mentorship is inspiring, motivating, and results-driven.”
“Mr. Ashraf is a highly dedicated educator. Through patient guidance and deep subject knowledge he helped my son strengthen his mathematical foundation and develop genuine confidence. Under his mentorship he excelled in mathematics competitions.”
Questions
