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 the terminal arm. We would draw a sketch of this on a graph, that has the x-axis and the y-axis. This initial arm is the […]

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 multiple rational expressions. Because it’s an equation and has an equal sign, you can solve it and find solution(s). The first step is to factor […]

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 variables. When it comes to multiplying, there are a few simple steps you need to follow. First, find the non-permissible values. Non-permissible values are variables […]
