Math is confusing enough without having to deal with lots extra choices. But if you’re a highschooler, there are choices galore. IB, AP Calc, regular Calc, Precalc, Algebra II with Trig, Algebra with Honors, Math Analysis… it all starts to sound like some strange underworld maze that probably has a ...

Law of Cosines: How to Use & Practice Examples
We have already seen how to solve triangles using the Law of Sines. Such problems involve two sides and two angles. The Law of Cosines (or the Cosine Rule) is used when we have all three sides involved and only one angle. The formula is: [latex latex size=”3″]c^{2} = a^{2} ...

The Law of Sines (or the Sine Rule) tells us that the ratio of a side length to the sine of its opposite angle is the same for all three sides. As a formula, it looks like this: [latex latex size=”3″]\frac{a}{sin\alpha}=\frac{b}{sin\beta}=\frac{c}{sin\gamma}[/latex] or [latex latex size=”3″]\frac{sin\alpha}{a}=\frac{sin\beta}{b}=\frac{sin\gamma}{c}[/latex] In the formula, a ...
