The range<span> of a function is the set of all the possible function outputs. </span>We know that <span>sin theta varies between -1 and 1 if we draw a graph. </span><span>According to the graph, the largest number that is an output of </span>g<span> is -1</span><span>, and the smallest number is 1</span><span>. Every number between them is also an output of </span>g<span> for some input. Therefore, the range of </span>g is [-1,1]. <span>
a = for a circle. We do not want to find the area for a whole circle. We only want to find the area for part of a circle. a hole circle is 360 degrees.
