Bring up the terms sine, cosine, and tangent and most students immediately get intimidated. But it doesn't need to be this way as these are simple trigonometric ratios that anyone can calculate. It's just a matter of remembering what each ratio is and plugging the measurements into the ratio. In today's free Geometry video, Professor Edward Burger explains these Trigonometric Ratios so all students can be fearless when encountering any of these terms. He even walks you through the steps of using a calculator for each, which can be helpful when the ratio is only a portion of a problem you are working. Today's video should help everyone realize that instead of being intimidating, sine, cosine, and tangent are incredibly helpful in determining different unknown measurements of triangles.
