I have a following relation
C = 1.2;
D = 9420;
E = -2.0;
B = 0.1973;
f = D*sin(C*atan(B*x-E*(B*x-atan(B*x))));
and I would like to X if Y = 9250.
When I use below code:
syms x0 y0
y0 = 9250;
eqn = y0 == StiffnessMagicFormula(D,C,B,E,x0);
slip_angle = vpasolve(eqn, x0)
I obtained following result:
But actually result should be around 6.8 .
I tryed also with functions: fsolve, roots and find but were all unsuccessful.
