How would you account for the variable a? Thanks for your time, really do appreciate it, and I know my syntax is wrong for my example in advance

Hi,

INT calculate then antiderivative at a given point . If you want the general solution, you can do (RPL mode, Indep var : X)

'A*X^2-4' INTVX

or

'A*X^2-4' 'X' 'X' INT

Not know about ALG mode but I suppose something like :
INTVX(A*X^2-4)
INT(A*X^2-4,X, X)

->

A.(1/3. X^3)-4.X

Verify that
- there is no 'A' variable already define in the directory you work or in parent directories
- No implicit multiplication with the 50G. AX is not A.X
