Q R Ax This picture shows part of the unit circle, and two points Q and P that are very near each other on the unit circle. The point R shares its x-coordinate with P and its y-coordinate with Q. The angle 0 in the picture measures 1.2 radians. This means that the point P must have a y-coordinate of about 0. 93 because sin(1.2) ~ 0.93. The tiny (incremental) increase in angle measure between P and Q is A0 = 0.05. Find the corresponding tiny increase in y-coordinates between P and Q, denoted Ay: Ay =
