Sin Cos Tan are designed exclusively for a digital interface; that’s not to mention trigonomic functions on a graphing calculator, but rather the Finnish synthpop duo consisting of Jori Hulkkonen and ...

Pages Sin, cos and tan Before we can use trigonometric relationships we need to understand how to correctly label a right-angled triangle.

For example- Sin 60° = √Fingers below 60° finger/2 = √3/2 Cos 90° = √Fingers above 90° finger/2 = √0/2 = 0 To calculate the tan ratios, flip the hand and assign the angles as shown below.

The trigonometric ratios sine, cosine and tangent are used to calculate angles and sides in right angled triangles. We are now going to extend trigonometry beyond right angled triangles and use it ...
