The Cos of 17 turned out to be 0.257, and 2 x 0.257 x 1357 x 1242 = 926,966.7. Subtracting 3,384,013 from 926,966.7 results in -2,457,046, which as a negative number cannot be turned into a square root according to my calculator.
What am I doing wrong here? Any help would be appreciated in this, so I can get to sinking. 
Good hunting! |
Multiply by -1, then do your little square root thingie.....
negatives are so easily taken care of with a well placed inverse.....
