Area Between Curves

After 4 long months of limits, derivatives, and integrals, it seems like calculus can solve just about anything. We started our final unit—applications of integration—by using our prior integration knowledge to calculate the area bounded by multiple functions. We will start with differential equations and revolutions in the upcoming year.

Terrific Titrations

We performed titrations of hydrochloric acid with sodium hydroxide every day this week in grade 11 chemistry class. Using a pH indicator and burets, we measured how much of each reactant was required for a neutralization reaction by detecting the instant the indicator in the solution turned pink, showing that the reaction was complete.

CSMC & CIMC

This week, we used problem-solving abilities to tackle 9 challenging problems in under 2 hours as part of the Canadian Senior and Intermediate Mathematics Contests (CS/IMC). The contest presented us with questions involving concepts in various areas of mathematics, which required short and full answer solutions. Top-ranking students will be recognized in the weeks to come.

Curve Sketching

The grade 11 calculus class began a new unit on curve sketching. Using their prior knowledge about the first and second derivatives of functions, students were able to sketch the slopes, concavities, and other key points of interest of various trigonometric, logarithmic, and rational functions.
