Will mark the ! lots of now find the following ( give the exact value where appropriate) a) cos (arctan (1))= and the angle is in quadrant 111 b) sin (arccos (1/2)= if the angle is in quadrant iv

The answer is a) cos(arctan(1)) and the Angle is in quadrant 111

The volume is 2212m cubed

The major difference is that a histogram is only used to plot the frequency of score occurrences in a continuous data set that has been divided into classes, called bins.  bar charts, on the other hand, can be used for a great deal of other types ofvariables  including  ordinal  andnominal  data sets.
