# Week 17- precalc 11

This week in pre calc we reviewed the idea of trigonometry and then learned new things to add on to what we already knew. So one of the things that we learned was the SIN LAW. The sin law is   The lower case letters are the side length measurements and the upper case letters […]

# Week 16- pre calc 11

This week in PreCalc 11 we learned how to solve rational equations.   Rational equations are equations containing at least one fraction whose numerator or denominator is a variable. There are two ways to solve rational equations, one of them is multiplying every term by each of the denominators or cross multiplication. Cross multiplication only […]

# Week 15- pre calc 11

This week in PreCalc 11 we revisited the idea of rational expressions and learned how to add together rational expressions with variables in the denominator. for example: when we add the rational expressions together the denominator needs to be the same so we take a common factor of the two denominators. And we always need […]

# week 14- pre calc 11

This week in pre calc 11 we learned how to determine the difference between and absolute value graph and reciprocal value graph. we know that an absolute value graph cannot have any negatives at all because when a number is in the absolute value symbol even if it is negative it must change to positive, […]

# week 13- pre calc 11

This week in PreCalc 11, we learned how to graph absolute value functions. An Absolute Value Functions is a function that has an expression within absolute value symbols. We were taught before that Absolute Values, was when the number is between the absolute value symbols must come out a positive. Example, | -2 | = […]

# week 12 – pre calc 11

This week in Pre Calc 11, We learned how to solve systems of equations using substitution. A way to solve a linear system or quadratic system or both is to use the substitution method. We do this by substituting a y-value in an equation with the other. to start you first substitute y in the […]

# Week 11- Pre calc 11

This week was a shortened week so we didn’t go over as much stuff as the previous weeks. We learned how to graph quadratic and linear inequalities in one variable and two variables. To graph a quadratic inequality you need to find the y- intercept and the vertex and use the clues given to graph […]

# Week 10- precalc 11

PreCalc 11 We did review for most of the week so this is one of the things i reviewed today.  so i revisited the idea of factoring polynomial expressions like we learned last year in grade 10, and like we learned in the previous units. For example, when we started the practicing of factoring expressions […]

# Week 9- precalc 11

This week we continued to go over quadratic functions. I learned that you could model problems with quadratic equations, for example: Find two integers with a sum of 24 and the greatest possible product. x+y= 2 product is a multiplication word so we know that we have to multiply it to find it meaning that […]

# week 8- pre calc 11

This week was a tough week coming back from spring break and my most struggle this week was trying to stay in focus the whole class since we had two weeks off I definitely missed a lot this week because I couldn’t keep in focus,  we learned how to graph quadratic equations, we learned that […]
