I am using a TI-89 Titanium ROM Version 3.10
I can use solve() readily for N equations and N unknowns, however:
I am trying to use the solve() function for Nodal Analysis with a Supernode
As you may recall, this means more equations than variables:
For example: (this is slightly modified from the real problem)
1] v1/2 + (v1-v2)/3 - 9 = 0 --> I am storing this STO > n1
2] v2/6 + (v2-v1)/3 - 7 = 0 --> I am storing this STO > n2
supernode
s] v2 + 5 = v1
or v1 - v2 - 5 = 0 --> I am storing this STO > n3
The supernode adds one more equation but there are only two variables
so:
solve(n1 and n2 and n3, {v1, v2})
returns -> false
This may be a trivial fix or more complicated, but I cannot see a workaround
How do I use solve() when there are N unknowns and > N equations ??
