The pillars are 10 feet tall and the walkway between the pillars is 20 feet apart. The arch that sits atop was created using two semi-ellipses m...

Re: Simplifying a messy expression

Yep, That's what I eventually got and like you it seemed to easy but I guess they are not always hard. Thanks for spotting the wrong sign in the problem on the last term. That's how the sign was shown on the handout so I am going to assume it was a typo. I wrote it all out by hand and it should be &...

Re: Simplifying a messy expression

That's correct. I don't have access to the radical symbols so sorry for the messiness. I got as far as figuring out the pattern. The problem as stated has a negative sign for the last term but I think you are correct that it s/b +. The assigment sheets have ben known to be a bit sloppy when it comes...

Simplifying a messy expression

Need to combine and simplify the following expression

1/(7-4*SQRT(3)) - 1/(4*SQRT(3)-SQRT(47)) + 1/(SQRT(47) - SQRT(46)) - 1/(SQRT(46)-3*SQRT(5)) +

1/(3*SQRT(5)-2*SQRT(11)) ......... - 1/(SQRT(5) - 2)

Isosceles Triangle

Need help with ...

Find all coordinate points A such that triangle ZAP in an isosceles triangle with base ZP where Z is the point (4/7,-9/4) and P is the point (7/2,1/11). No decimal answers which makes the soln(s) incredibly messy. I think there are two solns for A but not sure.

Difference two squares: pos. integer solns of x^2-y^2=120

Looking for a way to find all positive integers of x^2-y^2=120. Found some by trial and error but don't know how to find them all.
