Numerical methods can be used to solve one equation for a
single value or a set of linear or non-linear equations for
Numerical methods usually require an initial guess for the
The value of the initial guess(es) can influence the solution.
Numerical methods are not always successful in finding a
An acceptable tolerance rather than an exact answer is the
A variety of constraints such as minimums, maximum in
addition to target values may be applied to the solution. Numerical Methods
2T0 1 Given the equation for cable sag it
is easy to calculate h.
Use a Numerical Methods approach
to solve for T0 if h, w, and a are
T function(h,w,a) = ??? Numerical Solution

T0 = mid-span tension
Middle of curve
h = amount of sag TI-83 Solver
1. Select 0:Solver from the MATH menu
