This week in math 11 we learned about sin law. Sin law can be used to find missing sides or missing angles, and there are two different formulas to remember. the first one is for finding a missing side and that is It’s important to remember that a capital letter means its an angle and a lover case letter is…

# Week 16 – Math 11

This week in math 11 we started out last unit on Trigonometry. Some of the important vocal in this unit is, rotational angle meaning the angle formed from the initial arm, standard position meaning the initial arm is on the positive x-axis, and co-terminal angle meaning you use the same terminal arm and reference angle but you rotate clockwise. The…

# Week 15 – Math 11

This week in math 11 we learned how to add and subtract rational expressions. The first thing you are going to want to do when doing both adding and subtracting is to find the LCD (lowest common denominator), once you have found that you are going to want to re write the fractions and one big fraction with the LCD…

# Week 14 – Math 11

This week in math 11 we learned how to multiply and divide rational expressions. The most important thing to remember when doing this is to always factor out the expressions, this is important so that you can cancel out some parts to make the expression smaller and easier to work with. You also need to remember that when a question…

# Week 13 – Math 11

This week in math 11 we learned about reciprocal functions. These are hyperbolas created from a linear equation. Some important things to remember about these are the vertices and horizontal asymptotes and invariant points. The asymptotes are lines that the hyperbola will come very close to touching but never will, and the invariant points are -1 and 1 because the…

# Week 12 – Math 11

This week in math 11 we learned about absolute value functions. When graphing these functions its important to remember that these equations have absolute value bars in them so the graphs will stay in the positive side of the graph (Quadrant 1,2). For these equations the Vertex now becomes the critical point of the graph and this will come into…

# Week 11 – Math 11

This week in math 11 we learned about graphing linear inequalities in two variables. The solutions to these equations are represented by boundary lines that have shading on one of the sides, the boundary line can also be either solid or dotted/broken. You determine that by your greater than, less than, and greater than and equal to or less than…

# Week 10 – Math 11

This week in math 11 we learned how to solve quadratic inequalities. This is something that we started in math 10 with the solving part but determining wether x is greater then (x >), less than (x <), or is is equal to and greater then or less than ( X X ). The first thing that you are going…

# Week 9 – Math 11

This week in math 11 we learned how to change an equation from one form to another to find information we need for graphing. The three different forms of an equation are Vertex/Standard from, General Form and Factored Form. The way you change them is by using formulas that we have been using to awhile now, completing the square, and…

# Week 8 – Math 11

This week in math 11 we learned how to determine whether or not a parabola opens up or down(positive or negative), if it is congruent, and how to find the vertex. This can all be done just by looking at the function. For example, if the function looks like you know this function opens up because the is positive (keep…
