This week in math we learned about Sine Law in trigonometry. You can only use Sine Law when there is a number for an angle and its side (the side opposite of the angle). To use Sine Law you must… Continue Reading →

This week in math we learned about angles in standard form. When working with these angles it is best to work with a drawing to help get the answer. For the drawing you would use an x,y grid and label the… Continue Reading →

This week in math we learned about multiplying and dividing rational expressions. When working with rational expressions you must remember that the denominator cannot equal zero, so you must say what the non-permissible values, or restrictions are when answering the… Continue Reading →

This week in math we learned about reciprocal linear functions. The first thing you do with reciprocal linear functions is graph the original function. The second step you do is finding invariant points, which are the part of the line that… Continue Reading →

This week in math we learned about absolute value functions, when graphing absolute value functions it is similar too graphing normally, but you have to add another step. The first thing you do if it is a linear function is… Continue Reading →

This week in math we learned about graphing linear inequalities with two variables. When graphing linear inequalities you must make sure that y is by itself. For example, if you are given x + y = 10 you would then… Continue Reading →

This week in math we learned about equivalent forms of the equation of a quadradic function. In this lesson we were shown how to convert between the three different forms of a function to figure out different things about the… Continue Reading →

This week in math we learned about analyzing the quadradic  (also known as standard from or vertex form. When learning how to graph this quadradic you have to be able to understand what the parts of the function are. In… Continue Reading →
