Finding the Area bounded by two graphs

f(x) = $\sqrt3x+1, g(x)=x+1$

also this problem,

f(x)=1-x,g(x)=x^4 - x

I did one equation in Latex and one without. I would like to ask the forum members & admins if they could send me or direct me to a list of latex symbols and instrucions,etc. I guess I could just google it but hoping the admins have a preferred list.

ps.. I am off to my local wal mart to pick up some graphing paper and colored pencils,etc.

:D

Re: Finding the Area bounded by two graphs

Do you need help with Latex or do you need help with the problem. Are you supposed to use the washer method, the shell method... What?

Some versions of Linux come with latex and it's easy to install if it doesn't. Here are some resources for windows:

 You could at least use parentheses! This could be $\sqrt$(3)x+ 1 or $\sqrt$(3x)+ 1[/latex] or $\sqrt$(3x+ 1)[/latex]. Probably not the second, $y= \sqrt{3x}$+ 1 does not intersect y= x+ 1, they are tangent at x= 0. But the other two have different answers. [quote:11m2sykp]also this problem, f(x)=1-x,g(x)=x^4 - x
They intersect where $x^4- x= 1- x$ which is the same as [latex]x^4= 1[/latex and that has two real solutions, x= -1 and x= 1. So, determine which gives larger y in that interval, and integrate that function minus the other, from -1 to 1.
