how can i write and solve(plot) a one-variable equ. that consists of several one var. expressions?
for exaple:
(a0*z1^2+c0)+(a0*z1^2-c0)*cos(2*U0+m*Pi)+b0*z1*sin(2*U0+m*Pi)=0
is an equ. that a0 & b0 & c0 & z1 & U0 are all one variable equations that determined before.
all af theme depend to beta.
for example:
lambda=constant, c=constant, m=0 or 1.
k=2Pi/lambda
u=(k^2-beta^2), z1=alpha/u, U0=k*u*c
all of a0,b0 and c0 coefficients are expressions of "beta",
and therefore the principle equation depend only to beta.
and i want to get zeros of that equ. for an interval of lamda in a "for" loop.
