I intend to write a function in TI-BASIC on my CAS calculator that takes a mathematical expression (a quadratic specifically) as a parameter and ‘completes the square’.
To do this, I need to compute with the coefficients of the variable ‘x’ in the argument.
Is there a way to ‘extract’ the coefficients of x from the argument?
(A friend sensibly suggested to pass each coefficient as different arguments,
which would work, but seems messy and unnecessary).
Thanks!
Beg your pardon,
There’s a lovely polyCoeffs() function
