In this video I define the six trigonometric functions: sine, cosine, tangent, cotangent,
secant and cosecant, in a right triangle. Then, we review the special triangles for thirty
degrees, sixty degrees and forty five degrees, and after that I do a simple problem to
calculate a height using trigonometry.
