Adding a normal distribution curve to a histogram

Question

My code for the Histogram is

hist(rnorm(1000), prob=TRUE)

this gives me the proper histogram, but i need to plot the normal distribution over it. here's the code i tried for that:

curve(rnorm(x, 1000), -4, 1000, add=TRUE)

someone in my class said i needed that range so i threw in a million ideas of what it could be to make the plot (obviously -4,1000 didn't work). An help would be appreciated, I am super confused. it doesn't even throw an error message, R literally doesn't do anything when i run that second code.

This seems to be a similar question https://stackoverflow.com/questions/20078107/overlay-normal-curve-to-histogram-in-r — cgvoller, Oct 16 '21 at 22:42
`hist(rnorm(1000),prob=TRUE)` `lines(seq(-3,3,.1), dnorm(seq(-3,3,.1)), col='red')` — R. Schifini, Oct 16 '21 at 22:43
Obviously no one yet has shown you how to use the genuine R documentation? In R type `help('curve')` or `?curve` on how to specify it's arguments. — jay.sf, Oct 17 '21 at 05:11

I like the curve solution.

hist(rnorm(1000), prob=TRUE)
curve(dnorm(x), add=TRUE)
