[SOLVED] viete's relations problem 1. The problem statement, all variables and given/known data The zeros of the polynomial P(x) = x^3 -10x+11 are u,v,and w. Determine the value of arctan u +arctan v+ arctan w. 2. Relevant equations http://en.wikipedia.org/wiki/Viète's_formulas 3. The attempt at a solution I must admit I have no idea how to do this problem. I usually try to show some work but I have no clue how Vietes relations allow you to connect u,v,and w to the inverse trig functions. Sorry. Someone please just give me a nudge in the right direction.
