### Math 10

There are 5 things I found important in math 10, STOP PROCRASTINATING, studying regularly (doing the homework) and practicing yourself is key to understanding the unit and doing well on your tests. ASK QUESTIONS, if you don’t understand something even… Continue Reading →

This week we learned about slopes of a line segment, which is a measure of the steepness of the line segment, in simplest form. Slope is the ratio of the vertical change (rise) over the horizontal change (run): Slope= The rise is positive if we count up,… Continue Reading →

This week returning from Orlando I learned about domain and range. The Domain of a relation is the set of all possible values which can be used for the input of the independent variable. The Range of a relation is the set of all possible values of the output of the dependent… Continue Reading →

This week I learned about Intercepts. An intercept is when the X or Y axis are at zero on the graph. For an X intercept it is the point on the graph where the line crosses the x-axis, while for… Continue Reading →

This week we learned a technique/acronym to factor polynomial expressions CDPEU Can Divers Pee Easily Underwater Common Factor, Difference of squares, Pattern, Easy, Ugly C – Check if there is a common factor D – Check if there is a difference of… Continue Reading →

This week we learned about the difference of squares and how when you have two of the same expression binomials except that one is negative and the other is positive the middle terms cancel each other out, leaving a subtraction… Continue Reading →

This week one thing we learned was the different products that different equations can reach, one fully positive, one fully negative, and one both. The distribution of the following polynomials = (a+b)(a+b) = + ab + ba + = +2ab… Continue Reading →

This week we learned (or at least reviewed) a way of remembering how to multiply polynomials, of course it would be more difficult with more terms in each equation but the easiest way to understand is just with two binomials…. Continue Reading →

This week our subject was on trigonometry and more specifically this day was focused on finding the missing angles of a right angle (90 Degree) triangle. This missing angle was called “Theta” and could be found using SOH CAH… Continue Reading →

This week I learned that a cone is 1/3 of a cylinder or how a pyramid is 1/3 a cube, I also learned about slant height and how it is involved with pyramids and cones. To find the slant height… Continue Reading →
