This week in pre-calculus 11, we learn about two laws you can use to find missing angles and side in triangles. These laws are called: Sine Law and Cosine Law and are primarily used in non-right triangles. Today I will be explain my preferred law, the sine law. The “Sine Law” is used on a […]

Pre Calculus – Week 15
This week in Pre Calculus 11 we learned how to solve rational equations. A rational equation is an equation containing a fraction, whose numerator or denominator consist of a polynomial. While learning the lesson in class we discovered that there are multiple ways to solve these equations. My preferred methods are multiplying by a common […]
Week 14 – Pre Calculus 11
This week we learned about multiplying and dividing rational expressions. A rational number is a quotient of two integers, although in this unit we deal with rational expressions which are factions with polynomials as it’s numerator and denominator. Before explaining how to multiply and subtracts rational expressions there are a few things we must remember […]
Week 13 – Pre Calculus 11
This week we learned how to graph reciprocal LINEAR functions. At first glance, this lesson may seem hard, although after doing a few question you get the hang of it pretty fast. The first thing you need to remember is that the reciprocal is the flipped version of a function . I will start with […]
Week 12 – Pre Calculus 11
This week I am writing about graphing absolute value functions. Something to always remember about absolute values is that they are always positive, this is very important to remember when graphing. Consider a table of values: a regular table of y=x can have negative and positive values, although when graphing an absolute value function ( […]
Week 11 – Pre Calculus 11
This week in pre-calculus 11 we learned about graphing inequalities in 2 variables. One thing you must remember is that solutions for inequalities are shown on a number line and solutions for linear equations are represented on the axes lines on a graph (x,y). When graphing solutions to linear inequalities in 2 variables, they are […]
Week 10 – Pre Calculus
This week for my blog post, instead of talking about the new lesson we learnt, I chose to discus one of units I reviewed for the mid term… more specifically, a certain way of solving and finding the answer of a certain question that I struggled a lot with while learning this unit. With the […]
Week 9 – Pre Calculus 11
This week in pre-calculus 11, we learnt the equivalent forms of quadratic functions. There are 3 different types of functions: vertex/standard , general , and factored . Each of these different functions will tell us something different about the graph and parabola; the standard for will give us the vertex, the general will give us […]
Week 8 – Pre Calculus 11
This week I am choosing to write about how to graph the standard form (or vertex form) function . Something I was confused with at first was how this was compared to the general form function , I later learnt they share different meanings. The value of a in the standard form function will determine if […]
Week 7 – Pre Calculus 11
This week we didn’t learn to much because we spent most of the week reviewing for our unit test, we did learn 1 thing that was very useful when doing the quadratic formula. This weeks lesson was called “Looking at the discriminant”… the discriminate is the part of the quadratic formula that is underneath the […]
