He tabulated the length of a chord whose endpoints are separated by an arc of n degrees, for n ranging from 1 2 to 180 by increments of 1 2. In modern notation, the length of the chord corresponding to an arc of θ degrees is.

WebFree math problem solver answers your trigonometry homework questions with step-by-step explanations. 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.
