These ratios include sine, cosine, and tangent. Gage pins are sometimes used with sine bars and gage blocks to increase the range of measurements. After taking this class, a user should be able to ...

Let’s look at how to use trigonometric identities to calculate missing sides. \({sin~θ} = \frac {opposite} {hypotenuse}\) \({cos~θ} = \frac {adjacent} {hypotenuse ...

This circle has the centre at the origin and a radius of 1 unit. The point P can move around the circumference of the circle. At point P the \(x\)-coordinate is \(\cos{\theta}\) and the \(y ...

In an astonishing breakthrough, two young students from Louisiana have done what many thought was impossible: proving ...
