RE: Help with solve()
You can try the following App functions:
Solve.SOLVE(equation, variable to solve for, guess) Any variables have constants, store the values in those variables first before executing Solve.SOLVE. Example: X^2 + 2*T*X + 1 = T Solve for X when T = 3, with guess X = 0 3 > T (or T:=3) Solve.SOLVE(X^2 + 2*T*X 1 = T, X, 0) returns with 0.7639320225 To store the result in X: X := Solve.SOLVE(X^2 + 2*T*X 1 = T, X, 0) Function.ROOT( f(X) [=0], guess) Example: Find the root nearest to 3 for X^3  1.2*X  1. Root: 1.3861532869 Caution: ROOT could find a nearby extremum (spelling?) rather than a root. Example, try the above when X= 0.
