In this lesson our instructor talks about ratios in right triangles. First she talks about trigonometric ratios of sine, cosine, and tangent. Then she discusses trig function, and inverse trig functions. She finishes with a lecture on SOHCAHTOA. Four extra example videos round up this lesson.
Trigonometry: The study of involving triangle measurement
sine (sin) = opposite/hypotenuse
cosine (cos) = adjacent/hypotenuse
tangent (tan) = opposite/adjacent
