Hallo, I search a software to edit mathematics formulas. I have to write the formula along y axis and rotate of 90°. I use Equation Editor for writing equations, but if I export the equation with copy/paste and I try to rotate it, the image changes from vectorial to bitmap format and it reduces the resolution. Can someone help me? I have tried with Illustrator but when I read EPS files the graphics was wrong. Thank you Gabriele
