Trig Review Basic Trigonometry With Examples Youtube An introduction to trigonometric functions: sine, cosine, and tangent.about khan academy: khan academy is a nonprofit with a mission to provide a free, world. Other functions (cotangent, secant, cosecant) similar to sine, cosine and tangent, there are three other trigonometric functions which are made by dividing one side by another: cosecant function: csc (θ) = hypotenuse opposite. secant function: sec (θ) = hypotenuse adjacent. cotangent function: cot (θ) = adjacent opposite. Pretend you’re in the middle of your dome, about to hang up a movie screen. you point to some angle “x”, and that’s where the screen will hang. the angle you point at determines: sine (x) = sin (x) = height of the screen, hanging like a sign. cosine (x) = cos (x) = distance to the screen along the ground [“cos” ~ how “close. Trigonometry is an important tool for evaluating measurements of height and distance. it plays an important role in surveying, navigation, engineering, astronomy and many other branches of physical science. basic trigonometry involves the ratios of the sides of right triangles. the three ratios are called tangent, sine and cosine.
