![]() ![]() (diff basically takes the difference but one source told me that it's for derivative.) I've tried integrate, int, diff, and many other commands that I found under MATLAB but it doesn't do what I want it to do. Same as above, if I want to take a derivative of (x^2)+6 where x=2, what do I need to input in MATLAB? My major problem is that the MATLAB doesn't want to execute anything unless I specify x prior to that, which means it doesn't want to work in variable forms.īottomline, I want that equation integrated from 0 to 3 and substitute 100 into x to obtain value. Ignore that constant part unless it's needed to execute the command.) Let say there's a polynomial, 5x+6 and you want to integrate from 0 to 3 respect to x, how do you input in MATLAB? (I guess you can't figure out the constant once you integrate it since you don't have initial conditions. I found out that my thread shouldn't be posted under homework. ![]() First of all, I am not trying to "spam" subforums. ![]()
