TRIGALGE - Easy Calculation
Find x such that Ax+Bsin(x)=C.
Input
The first line denotes T (number of test cases). 3T integers follow denoting A,B and C for every test case. (A >= B > 0). All Integers are less than 100000.
Output
T real numbers rounded to 6 digits one in each line.
Example
Input: 1 1 1 20 Output: 19.441787

No clue how 6 iterations are working for some people, i tried 6 iterations by initialy guessing sinx to be 1 and also guessing sin x to be 0. Had 2 WA. Went for 50 iterations. AC it is .. Learnt Newton Raphson :) |

Got WAs due to fewer iterations :P |
