Parallel line equations.I've figured out how to do this just fine but I have one small problem. Aloha Nui means Goodbye. #2 20051205 00:24:14
Re: Parallel line equations.All of that's right, and then you just have to finish it off by multiplying out of brackets. Why did the vector cross the road? It wanted to be normal. #3 20051205 00:27:33
Re: Parallel line equations.I did indeed get to that but the gradient is supposed to be an integer (whole number). Last edited by rickyoswaldiow (20051205 00:32:43) Aloha Nui means Goodbye. #4 20051205 00:49:51
Re: Parallel line equations.The book is wrong. "In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..." #5 20051205 01:30:56
Re: Parallel line equations.The book is often wrong, will you be my A level tutor instead? Aloha Nui means Goodbye. #6 20051205 01:33:25
Re: Parallel line equations.I think I've been ignoring the  on the gradient and am visualising a reflection of the line. Aloha Nui means Goodbye. #7 20051205 01:52:46
Re: Parallel line equations.Ah, so you did mean a slope of 3/2 after all. Last edited by Ricky (20051205 01:54:05) "In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..." #8 20051205 01:55:59
Re: Parallel line equations.Brilliant, thanks. Last edited by rickyoswaldiow (20051205 02:01:04) Aloha Nui means Goodbye.
