Is this equation possible to solve (for d)?
Another simpler similar equation is x=cos(x), which also does not a symbolic solution .
x=cos(x) has a definite solution of about .739 - but I think you mean x=cos(y), which has a symbolic solution in y=±acos(x)+2*pi*n.
there are an infinite number of angles that will solve that equation.
vlad777,
Sure it is. But you have to calculate a root of an equation, which you cannot do until you know the values of v, r, and w. Those values determine the value of the root, and what form the equation you have to solve is. It does not appear to have a symbolic solution. Another simpler similar equation is x=cos(x), which also does not a symbolic solution .
Ratch
How do I calculate root (for this particular equation) if values for v,r,w are known?
(Please take some values for v,r,w ;I did not because I don't know what is a good example.)
Can you please tell me the name of this program?
x=v*d+r*sin(w*d)
Is this equation possible to solve (for d)?
Many thanks.

Is there an infinite series representation of d?
Hmm... your function wasI posted a recursive solution back in post #9. You can use that to create a series if you wish.
