User friendly differential equation solver
This is kind of hard to explain.
I am creating a numerical solver that gets input from students in the form of an equation. An example being x^2 + y^2. I'd like to take this input and somehow put it into VBA as is.
This equation is going to be in a for each loop, where the values of x and y are changing with each iteration.
For i = 1 To n
m = x^2 + y^2 'Equation input from students
y1 = y + m * dx
y = y1
x = x + dx
I pretty much need to paste the input from the students into the m variable, where x and y are declared variables as well.
Is this even possible? Variables within a string.
