function composed from another functions - "solve" does not work
function composed from another functions - "solve" does not work
(OP)
Hi,
I have a function composed from another 3 functions and I like to obtain points where f(x) = 0. So in attached I expect 4 values, but solve does not work. Please help.
Regards

It maybe that mathCAD's symbolic solve command cannot solve for x when MYY(x) is a function with embedded if/then logic. Either way, pretty impressive worksheet.
Oh..and polycoeff *is* a MathCAD function in my version (v14). Maybe Occupant's conclusion isn't so obvious. ;)

I have to admit, I am not using v14 but v13 and I had to go back to find out. If you're right, how come "polycoeff" turned red (in V14-M020 and V13, of course) and I got "this variable is undefined". If it was a function recognized by Mathcad, I should have gotten "this function does not apply here" or some such thing.

polycoeff(vx, vy) Takes two real vectors of the same length vx and vy and returns the coefficients of the interpolating polynomial function
