1 + 8000x^3=28800x
pls am stuck here, how do i get a result for x form the equation above. thanks
There are various numerical methods to find a solution. Once you pin one down, the other two are easy. That first on is the tricky one, but, off the top of my head, it can't be very far from zero (0). You tell me why this is so.
Shoot for x = 0.000034722222234 and see how far it gets you. Tell me how YOU managed to find it.
Not a bad idea! The "1" is so small compared to the other coefficients that this should give you a reasonable "first approximation". Then use a simple "perturbation method" to improve the approximation. If your first order approximation is , let to get a cubic equation in y. Make the same kind of reduction to get an approximate value, for y, then repeat with .
