Evaluate the composition of trigonometric functions by creating a right triangle. In this video we will evaluate the tangent by given the ratio for cosine. To do this we will use right triangle and ...

In this video, I show you how to set up a word problem and solve it using the trigonometric ratio. In this case, we will find the height of a building using the tangent function. I make short, ...

The sides of right-angled triangles are labelled opposite, hypotenuse and adjacent. Trigonometry explores the relationship between sides and angles in right-angled triangles. The hypotenuse is the ...
