Hello. I would be thankful if someone would give me a help in finding a solution for x cos(x) = -(3pi+2)/2pi Regrads.

This almost certainly does not have a simple closed form solution in simple terms. Numerically its easy to find approximate solutions: x = 2.420631593 is ~the smallest positive real solution RonL
