Using a Calculator to track down Sine and Cosine

Using a Calculator to track down Sine and Cosine At \(t=\dfrac\) (60°), the \((x,y)\) coordinates for the point on a circle of radius \(1\) at an angle of \(60°\) are \(\left(\dfrac,\dfrac\right)\), so we can find the sine and cosine. We have now found the cosine and...
