Week 17 – PreCalculus 11

We started off our unit of Trigonometry or “trig” for short. In this unit we where introducted to triangles that go past 90 degrees even though it this may seem a little strangle it is quite simple.  As we where taught in grade 10 we ended only using the Soh Cah Toa method and pythagorous…

Week 16 – Pre Calculus 11

Solving Rational Equations To solve rational equations we must cancel out the denominators. To do this we must multiply by each denominator, this will cancel them out but because we have to do the same for everything in the equation, we will have then multiply the numerators by the values that were not canceled out.…

Week 15 – Pre Calculus 11

This week in Pre Calculus 11 we were introduced to the concept of dividing and multiplying rational expressions. The first step to solving these expressions is to simplify as much as possible. Doing this it will save you lots of unnecessary steps down the road. Just like in dividing fractions the main this you must…

Precalculus – Week 14

This week in Precalc 11 we were learning what an absolute value and what a reciprocal function looks like. Both have similarities but also many differences. Both an absolute value graph and reciprocal function graph can either be linear or quadratic. An absolute value graph looks either like a V or W if quadratic and…
