And Sine, Cosine and Tangent are the three main functions in trigonometry. They are often shortened to sin, cos and tan. The calculation is simply one side of a right angled triangle divided by another side ...we just have to know which sides, and that is where sohcahtoa helps. For a triangle with an angle Î¸, the functions are calculated this way: Sine Function: soh... s in(Î¸) = o pposite / h ypotenuse. Cosine Function: ...cah...hey are often shortened to sin, cos and tan. The calculation is simply one side of a right angled triangle divided by another side ... we just have to know which sides, and that is where sohcahtoa helps.
