WebThink about the unit circle. Sine of theta is the y value of a point on the unit circle and cosine of theta is the x value of the point on the unit circle. 0 degrees is straight to the right and then as theta increases you move counter-clockwise. Thus when theta is 90 degrees you are at the point (0,1). Hence sin(90)=1 and cos(90)=0. WebThe unit circle is the golden key to actually understanding trigonometry.
