WebThe reason it works is because you can describe points in [-1,1] in multiple ways: algebraically just as "x" and trigonometrically as expressions like sin (𝜃) or cos (𝜃). Look at the relations among trig functions, such as. (sec 𝜃) 2 - 1 = (tan )2. WebThis section looks at Sin, Cos and Tan within the field of trigonometry. ... This video will explain how the formulas work. The Graphs of Sin, Cos and Tan - (HIGHER TIER) The following graphs show the value of sinø, cosø and tanø against ø (ø represents an angle). From the sin graph we can see that sinø = 0 when ø = 0 degrees, 180 ...
