In this week, I learned about the sine law and the cosine law. I chose these topics because I never learn about these law in my life. Also, I thought these laws are really useful. The sine law: In every triangle ABC,   I tried to solve practice paper number 8.   At first, check…Continue Reading Week 17 in Precalc 11 – (The sine law and the cosine law)

In this week, I learned about special triangles. I chose this topic because I learned about this before but I forgot about what is the element of this and how to use this triangle. These are special triangle which I learned in class.   I show example of how to use this angle. Use left…Continue Reading Week 16 in Precalc 11- (Special Triangles)

In this week. I learned about rotation angles and reference angles. I chose this topic because I have never learned about this topic before took this class. I learned some vocabulary about this. Rotation angles: It is formed by rotating an initial arm (or initial side) through an angle 0 about a fixed point (the…Continue Reading Week 15 in Precalc 11- ( Rotation angles and reference angles)

In this week, I learned about solving problems involving rational equations. I chose this topic because this topic has various of way to solve. Also, I didn’t understand completely before. I gained useful information. I learned about relationship between speed, time, and distance. It’s useful to solve “Problems invloving distance, speed, and time” Speed= distance…Continue Reading Week 14 in Precalc 11 – ( solving problems involving rational equations)

In this week, I learned about Rational expressions. I chose this topic because this topic is significant in unit 6. I learned some infornations about this topic. The quotient of two integers( eg. four-sevenths) is rational number. Similarly, the quotient of two polynomials is called a rational expression. Reduce the rational expressions by dividing out…Continue Reading Week 13 in Precalc 11 – (Rational expressions)

In this week, I learned about interval notation. I chose this topic because I didn`t get it first time. Thats why I chose this topic. I knew the information about interval notation. Interval Notation : It is a shorthand way of writing an inequality. ・A closed bracket ［ or ］indicates that we include the endpoint….Continue Reading Week 12 in Precalc 11 – ( Interval notation )
