Question

How do I reduce this fraction:
y/x+x/y
/
1/xy

Answer 1

combine fractions in numerator
y/x + x/y = (y^2+x^2)/xy
multiply by reciprocal of denominator
(y^2+x^2)/xy * xy/1 = y^2 + x^2

Answer 2

\[\frac{\frac{y}{x}+\frac{x}{y}}{\frac{1}{x y}}=\frac{\frac{x^2+y^2}{x y}}{\frac{1}{x y}}=x^2+y^2 \]

Answer 3

yeah that looks better

Answer 10

Mathematic 8 will copy and paste LaTex. it is done in two steps.
First right click on the Mathematica expression. Then holding down the right click button, slide down to the Copy As which puts up a secondary window offering Copy As LaTex or MathML.

Considering the technology embedded in this program and the years of development, they essentially give it away to students and teachers.

Answer 11

\[\frac{\frac{3}{y}}{\frac{2}{x}+1}\]

Answer 12

Thank you robtobey. I will read this and look into it...

Answer 13

I don't have Mathemataica at our college.

Answer 14

I'm clicking on Equation editor and using the LaTeX frac{a}{b} command.

Answer 15

I can learn the LaTeX commands on an as-needed basis, as I go along.

Answer 16
