Question 675195
For x's less than {{{pi/4}}}, cos(x) > sin(x). So this rules out (a) and (c) since they have cos < sin. So only (b),  (d) or (e) can be correct.<br>
Next, when a number is multiplied by a number between 0 and 1, the result is smaller. (Remember this if/when you take the SAT!) cos(.1) and sin(.1) are both numbers between 0 and 1. So when we multiply cos(.1)*sin(.1) we end up with <i>a result that is smaller than both!</i><br>
So the product of cos(.1) and sin(.1) is the smallest number, cos(.1) is the largest and sin(.1) will be the in-between number. Answer (b) has these in the right order.
