# Week 18

Top 5 Things I Learnt in Pre-Calc 11 Cosine Law Useful for every triangle Easy to use Parabolas Always wondered how they looked on graph Interesting and “fun” with absolute values Arithmetic Sequences How to find n amount of terms Found this very interesting and easy I liked learning this because it could also be […]

# Week 16

One thing we learnt this week is how to use the sine law, it can only be used if there is an angle and its opposite. And it is also super easy to use and remember which is why I love it. A tip is to flip the equation if you are looking for an […]

# Week 17

This week we learnt how to use the cosine law, i found this very valuable because it can be applied to all triangles even right!

# Week 15- Adding Rational Expressions

One of the things we learned this week is how to add rational expressions i found this similar to regular fractions so this was kinda fun. Its a little bit tricky but i like that.

# Week 14- Dividing Rational Expressions

This week we learned how to divide rational expressions, i found it pretty simple but need to watch the small details and remember to write down the restrictions before I flip.

# Week 13- How to Algebraically Solve an Absolute Value Equation

One of the things we learnt this week is how to algebraically solve absolute value equations. to be honest i found this a little tricky but after doing a few questions I got the hang of it. I sometimes still forget to do the last step though. Where we check to see if its true

# Week 12- Absolute Value Functions

One of things we learnt this week is how adding absolutes “signs” will change an equation and a graph. Above are two examples one a linear and one a parabola and you can see the different between the equation with and with out absolute “signs”. You can see how the output or the y-value cannot […]

# Week 10- Linear-Quadratic Systems

This week we learned how to algebraically solve a Linear-Quadratic system. I found this kinda tricky because there are so many steps and you had to use skills from the past.

# Week 9 -Equivalent Forms of Quadratics

How to change from General Form to Standard Form. This week we learnt how to convert from General to a more helpful form of Standard or Vertex form

# Week 8- Quadratics

One thing we were introduced to this week was Standard Form. This is my favorite from when graphing because it tell you so much about the graph. Standard form looks like: \$latex\ y= a(x-p)^2 +q   Where a cannot equal 0 ex. Y=1(x-1)^2 +2 The A value tell you which way the parabola open (positive up/ negative down) […]
