hi to everyone!i need help for my assignment in our numerical analysis.our instructor asked us to solve a linear equation using turbo c language.Can anyone help me with this problem,a simple sample code will do.Ex.f(x)=2x^3+x^2

2x is multiplication; you can do it with 2 * x . The ^ operator exists in C, but not in the way that formulae use it. It means bitwise exclusive-OR instead of exponentiation. Turbo C supports the pow() function though, so you can use that:

then we have to get it's 1st derivative, in math the 2nd equation would be like this:
f'(x)=6x^2 + 2x

my problem now is how to solve for it's derivative.
Note: this is not a fixed program the user is asked to input the f(x) that he wants to be solved,whatever equation that is being inputed by the user must get a correct answer.TY

Are you sure this is linear equation or linear function? I'm pretty sure your examples are linear functions.. Linear equations are solved like so:
Solve for x and y:
x+2y=8
3x-2y=0

Hi, as I was told that my code doesn’t scale well at all, I thought perhaps I’d try to get a better understanding of interfaces/abstract classes and classes and the relationship between them.
I don’t want at this stage work on a big separate project as I've already got plenty ...

OK, so HostGator for some reason no longer allows gcc/g++ access unless you have a Designated Server account, which is a lot of money to spend just to compile my "Hello World" program. Thus I figured I'd compile at home, then upload. Program is your regular old bare-bones Hello World ...

Hi. I have a form with list box : lst_product, datagridview : grd_order and button: btn_addline. lst_product has a list of product ids selected from database (MS Acess 2013) , grd_order is by default empty except for 2 headers and btn_addline adds rows to grd_order.
