x/y + y/x = x^2 + y^2/xy

Thanks

Do you mean x/y+y/x=(x^2+y^2)/xy

Because your original equality is false

Clearly you implied (x^{2}+y^{2})/xy as opposed to x^{2}+(y^{2}/xy) and to see why this is true, do you know how to add fractions such as 1/2+2/3?

Yeah I just forgot my brackets... It came when simplifying this trigonometric equation and just changed from the one form to the other and I got so confused so I looked at what happened and came to that equation, yes but I'd only make the denominators 6 and then add the numerators.

So, what did you do to 1/2+2/3 to solve it, and how can you apply that to your original question?
