This is my last blog post for Precal 11 and I will be going over my top 5 things from Precalc 11.
- Factoring Trinomials. This was one of my favourite parts of PC11 because I found it super easy to understand the concept, especially since I can think of factors quickly.
- Sine Law. This topic was extremely easy to understand because it only needed 3 pieces of info out of 4 and it works with more complex triangles that are not 90-degree triangles.
- Quadratic Formula. The quadratic formula was really annoying to remember in the beginning but after you have it memorized you can find answers that factoring can’t. The discriminant will also tell you how many solutions the equation has.
- Vertex Form. This formula was really easy to use and remember. Once you understand what each letter/number means. It made it really easy to graph it out. Once you learn how the stretch value works, it makes graphing so easy.
- Multiplying/Dividing Fractions with Nomials. This topic was easy to understand and helped a lot especially when they are trinomials that can be factored and cancelled out.
