Learn right triangle trigonometry in this video by Mario's Math Tutoring. We discuss the sine(sin), cosine(cos), tangent(tan), cosecant(csc), secant(sec), and cotangent(cot) functions. Further we go through examples to find the missing side in a right triangle. We also discuss the soh cah toa acronym for remembering these trig ratios. We also discuss the 30-60-90 and 45-45-90 special right triangles, as well as the angle of elevation and angle of depression.
