They created tables of sine values (actually chord values, in really ancient times, but that more or less amounts to the same problem) by starting with $\sin(0^\circ)=0$, $\sin(90^\circ)=1$ and then using known formulas for $\sin(v/2)$ to find sines of progressively smaller angles than $90^\circ$, and then formulas for $\sin(v+u)$ to find sines . sin = Commonly used angles. Since sin( 12) is positive, then only the positive answer is accepted. . The online unit circle calculator allows you to determine the sine, cosine, and tangent value for an angle that helps to figure out the coordinates on the unit circle. Split into two angles where the values of the six trigonometric functions are known. Only the sin and cosec angles are positive and the remaining angles are negative in the second quadrant.
