here is the original equation

One part at a time
the numerator is:
-4%2ASQRT%28+36+%2Acos%280%29%29+=+-4%2Asqrt%2836%2A1%29 = -24
the denominator is:
4%2Asin%2890%29+=+4%2A1 = 4
numerator over denominator is:
-24%2F4+=+-6
So, we have
sqrt%28-6+-144+%2B+125%29+=+sqrt%28-25%29 = 5i.
Now,
5i -16pi/2 is the answer.
