This page explains the sine, cosine, tangent ratio, gives on an overview of their range of values and provides practice problems on identifying the sides that are opposite and adjacent to a given angle. The Sine, Cosine and Tangent functions express the ratios of sides of a right triangle.
A small toy attached to the end of a slinky (or spring) bobs up and down according to an equation of the form d = a cos(bt). The motion of the toy starts at its highest position of 5 inches above its rest point, bounces down to its lowest position of 5 inches below its rest point, and then bounces back to its highest position in a total of 4 ...
Find [tex]\cos\alpha[/tex], [tex]\tan\alpha[/tex], [tex]\cot\alpha[/tex], if [tex]\sin\alpha = {\frac{5}{13}}[/tex] and [tex]{\frac{\pi}{2}} \alpha \pi[/tex]. Solution: [tex]\alpha[/tex] belongs to the II quadrant => [tex]cos\alpha[/tex] 0, and [tex]cos\alpha=-\sqrt{1-sin^2\alpha}=-\sqrt{1-{\frac{25}{169}}}=-{\frac{12}{13}}[/tex] [tex]tan\alpha ...
