I am trying to graph the function y=f(x)=1/x over the interval (-5,5). But I am getting an error message. Please see below. I am getting the error message: *Error in xy.coords(x, y, xlabel, ylabel, log) : * * 'x' and 'y' lengths differ*
You have "y < 1/x" rather than "y <- 1/x"! So "y" is not assigned and presumably you have some old "y" variable in your global environment that is used and does not match the length of "x".
x x <- seq(-5, 5, 0.01) y < 1/x plot(x,y, type='l', xlim=c(-5, 5), ylim=c(-5, 5), xlab = "x", ylab = "f(x) = 1/x", lwd = 2, col ="red") abline(h=0, lty=2, col = "blue") abline(v=0, lty=2, col = "blue") axis(1) axis(2) title(main="The Graph of f(x) = 1/x") any help will be highly appreciated. with thanks abou
