Hi All,
I have a work problem that I require a formula to be reversed it is a graph and I need to solve this so I can put the formula in to control an actuator between 0% and 100% with finer control rather then using a lookup table and picking 20 or 30 random points. I have used this formula to plot look up tables in excel but the control is not smooth as you can imagine every time I have a "gap" in the points i have chose my control is essentially stopped until the next point the controller is not smart enough to graph it.
y = (0.00000256x^4) - (0.0008x^3) + (0.0932Xx^2) - (4.95x) + 110
if someone could reverse that to find x or show me how to solve one part of the brackets that would be a great help.
Thanks in advance,
