Advanced Trigonometry 2

In this lesson, we will learn how to find the area of a triangle using the formula A = ½ absinC.

In this lesson, we will learn how to use the formula A = ½ absinC to find a missing length by rearranging the formula.

In this lesson, we will develop the skill of knowing when to apply the sine and cosine rules. We will be able to identify cases that do and do not allow us to use the sine and cosine rules.

In this lesson, we will apply the sine and cosine rules as well as the formula A = ½ absinC in order to solve trigonometry problems.
