Hi all,

I was trying to solve a problem but I found a difficulty, which I summarize in an example:

Good behaviour:

define f2(x,y)=4x+2y+1
	done
solve(f2(x,y)=0, x)
	{x=((-y)/(2))-((1)/(4))}

Bad Behaviour?

define f1(t)=4x(t)+2y(t)+1
	done
solve(f1(t)=0,x(t))
	gives a bad argument error

Shouldn't it result in sth like:

{x(t)=((-y(t))/(2))-((1)/(4))}

?

Thank you.

Hi.
I think SOLVE function can solve an equation with exact variable (like x) not for a function. you can use

You should first define x(t), then f(t) and use Solve(Expane(f(t))=0, t)
