Hi, I was wonder if someone could tell me the correct syntax for the graphing calculator: I need to draw y=(2x+2y)/3x divided by (x+y)/2x I've tried every different combination I can think of, even multiplying the second part by the reciprocal but get a syntax error every time. Cheers. |

Inline syntax is tricky. Use: y=((2x+2y)/3x)/((x+y)/2x) That is, enter as a fraction of the fractions. ---------------------------------------- Principal Skinner |

Thanks for your reply but I tried that and it just keeps saying: OOPS! Syntax Error I tried entering ((2*x+2*y)/3*x)/((x+y)/2*x) in the input line as well, all to no avail AAAARRRRGGGHH!!!!! What's going on? I've spent about 4 hours trying to get this to work now. |

Enter:y=(2*x+2*y)/(3*x)/(x+y)/(2*x) using Advanced equation graphic calculator. You get: And this is the graph you get: I hope this helps. |

I can't be sure what you are entering: I suggest copy and paste might work. But... Your entry of: (2x+2y)/3*x is not what you want, because the order of operations then puts the last x in the numerator. You need to use parentheses and keep them paired correctly: (2x+2y)/(3*x) will work. ---------------------------------------- Principal Skinner |
