Solve the Equation

Solve the equation:

        p*e^-x + q*sin(x) + r*cos(x) + s*tan(x) + t*x² + u = 0
        where 0 <= x <= 1. p,q,r,s,t,u are variables.(where 0 <= p,r <= 20 and -20 <= q,s,t <= 0).

For each set of input, there should be a line containing the value of x, correct upto 4 decimal places, or the string "No solution", whichever is applicable.

eg:

Input

0 0 0 0 -2 1

1 0 0 0 -1 2

Output:

0.7071 

No Solution
