Hi, I want to find the solution of a transcendental equation. I got three solutions to the equation. Typically, the solution for 'b' are either greater than Pi or less than Pi [including the value at Pi]. Please suggest that whether the value greater than or less than to be taken. Using MATHEMATICA: f = Pi - b - 1.2*Sin[b]; Rts = Reduce[f == 0, b, Reals] * Solution for Pi = b + XSin[b] b == 2.11485 || b == 3.14159 || b == 4.16833.
Hi, Simpson and Cardin, thanks for your help. But the difficulty is if you go through my post , I got the same soutions as you have obtained. The point is for a particular value of X [here X = 1.2], three solutions are there. Now, which of the two roots [excluding the root at b = Pi] are to be considered and why.
NSolve[Pi - x - 1.2*Sin[x] == 0, x, Reals, 15]
{{x -> 2.11485436221882}, {x -> 3.14159265358979}, {x -> 4.16833094496076}}
.
Plot[Pi - b - 1.2*Sin[b], {b, 0, 5}]
