Re: Determine the approximate values of sinθ and cosθ from the digram below

If your points are on the unit circle centred at the origin, then \(\displaystyle \displaystyle \begin{align*} x = \cos{(\theta)} \end{align*}\) and \(\displaystyle \displaystyle \begin{align*} y = \sin{(\theta)} \end{align*}\).

This, of course, depends on what $\theta$ is since it is not marked on the diagram. Maybe it's the angle made by the axis of symmetry of the letter "o" in the Google logo (which is typeset in the Catull font). (Smile)
