Week 17 in Precalc 11

This week in math we learned about the Sine Law. The Sine Law includes an equation which you can use to solve triangles, as long as you have three clues:

Week 16 in Precalc 11

This week in math we learned about angles in standard form. First, we need to know some terminology. The rotation angle is the angle formed between the initial arm and

Weel 15 in Precalc 11

This week in math we learned how to solve rational equations. A rational equation is like a rational expression, but in an equation (so there’s an equal sign) with most-likely

Week 14 in Precalc 11

This week in math we learned how to multiply and divide rational expressions. A rational expression is a quotient of two polynomials, so it’ll look like a fraction but with

Week 13 in Precalc 11

This week in math we learned how to graph linear reciprocal functions. The parent function would be in the format: f(x)=mx+b, but the reciprocal of that would look like f=.

Week 12 in Precalc 11

This week in math we learned how to solve systems algebraically when one is a linear system and the other quadratic using substitution. We learned about this method in Math

Week 11 in Precalc 11

This week in math we learned how to graph quadratic inequalities in two variables. Some basic information to know first is what the signs mean, e.g. < or > means

Week 10 in Precalc 11

This week in math we learned how to solve quadratic inequalities using a sign chart. To recall, in previous years we had learned how to solve linear inequalities and how

Week 9 in Precalc 11

This week in math we learned how to convert quadratic functions into general form, factored form, and standard form from other forms. General form is y=a+bx+c, where c is the

Week 8 in Precalc 11

This week in math we learned how to determine the properties of a quadratic function. On a graph, a quadratic function looks like a U or upside down U, it’s
