Question 1177773
<font face="Times New Roman" size="+2">


Your range function is incorrect.  Repost with the correct function.  Make sure you use parentheses so that it is clear whether factors belong in the numerator or denominator.  There is no factor of "8" in the function anywhere, and all of the sin function's argument belongs inside of the parentheses.
