Review with free study resources
Conditional Probability and Bayes: Choose the Right Denominator
Start with counts, distinguish “given” from “and,” derive Bayes’ formula and test independence with a frequency tree and four explained exercises.
Integrating Factors for First-Order Linear ODEs
See why an integrating factor works, normalize a linear ODE, apply an initial condition and keep the correct interval. One worked example, a graph and three explained questions.
A Wave in Space and Time
Read a wave snapshot and a particle’s time trace. Connect amplitude, wavelength, period and speed, with two graphs and three explained self-checks.
How to Choose an Integration Method
Compare substitution, integration by parts, partial fractions and trigonometric substitution, with sign-aware radical choices, worked examples and progressive checks.
Free-Body Diagrams and Friction: From Forces to Equations
Choose a system, distinguish static from kinetic friction, and turn a force diagram into equations. Compare horizontal and angled pulls with original diagrams and worked practice.
Cancelling Factors: Why the Missing Input Stays Missing
Learn why cancelling a factor preserves an excluded input and distinguish a function value from a limit, with a worked example and three self-checks for Concordia MATH 203 and McGill MATH 140.
Row Operations: Why the Solutions Stay the Same
Understand reversible row operations, solve and check a linear system, and distinguish one, no and infinitely many solutions. Original practice for Concordia MATH 204 and McGill MATH 133.
Before Calculus: 10 Algebra Skills You Should Know
Ten essential algebra skills with worked examples, common mistakes and self-checks: a practical starting point before university or CEGEP calculus.
Eigenvectors and Eigenvalues: See the Geometry
Recognize invariant directions, find eigenvalues and eigenspaces, and check Av = λv. Two worked examples, two diagrams and five questions with hints and explained answers.
Electric Field vs Electric Potential: Signs, Units and Worked Examples
Distinguish field, potential, force and energy. Compare two midpoint cancellations, read a potential graph and work through five explained practice questions.
Kirchhoff’s Laws: Circuit Signs and Worked Examples
Choose current directions, write junction and loop equations, and interpret negative currents. Two worked DC circuits and five exercises with hints and solutions.
Work, Energy or Momentum: Choose the Method
Choose a system and interval to connect work, energy and momentum. Guided collision and force–position practice, with an optional centre-of-mass and relative-displacement extension.
Motion Graphs: From the Story to the Equation
Translate a motion story into position, velocity and acceleration graphs. Read slopes and signed areas, choose valid kinematics equations, and try six explained questions.
Volumes of Revolution: Build the Cross-Section First
Build volume integrals from slices, radii and bounds. Practise disks and washers, then compare washers with cylindrical shells in an optional worked example.
Torque and Static Equilibrium: Find the Perpendicular Lever Arm
Find perpendicular lever arms, choose torque signs and pivots, and check force and torque balance. Three worked examples and six questions with hints and solutions.
Connected Objects: Contact Forces, Tension and Pulleys
Find contact forces and pulley tension with separate force diagrams. Three worked examples and four solved questions include stacked blocks and slipping.
Circular Motion: Force Diagrams and Centripetal Acceleration
Choose the inward direction, draw real forces and check friction or contact limits. Three worked examples and four questions with hints and explained solutions.
Mechanics: Six Questions to Check Your Setup
Practise choosing a system, drawing forces and writing signed equations through six mechanics questions with optional hints and worked solutions.
