RE: Q: lefthand/right hand side of equation


Robert:
	Here's one way:
a+b==c+d /. x_+y_==z_+a_->x+y
which gives you the left-hand side, or 
a+b==c+d /. x_+y_==z_+a_->z+a
which gives you the right-hand side.

	Of course, you might want more general pattern matches if you intend
to use this with other equations.

	Best,

	Harvey

Subject:	[mg26872] Q: lefthand/right hand side of equation

hello!
maybe a rather simple question:

if i have an equation, how can i get the left/right hand side?

e.g.

eqn={a+b==c+d};

i'd like to get something like:

l=a+b
r=c+d

thanks,

robert
