Similarly (7) comes from (6). (8) is obtained by dividing (6) by (4) and dividing top and bottom by

      Restrict Cosine Function • The restriction of a cosine function is similar to the restriction of a sine function. • The intervals are [0, π] because within this interval the graph passes the horizontal line test. • Each range goes through once as x moves from 0 to π. Inverse Cosine Function • Once we have the restricted function, we are able to proceed with defining the inverse cosine

      2xcos(x2)dx. This is not a “simple” derivative, but a little thought reveals that it must have come from an application of the chain rule. Multiplied on the “outside” is 2x, which is the derivative of the “inside” function x2. Checking: d dx sin(x2) = cos(x2) d dx x2 = 2xcos(x2), so Z 2xcos(x2)dx = sin(x2)+ C.
