I'm trying to draw a graph of the function 

 h(t)  =  200 - (1/2)9.8t^2 + 8t

but I keep receiving unexpected symbol errors when I do:

curve(200 - (1/2)*(9.8)t^2 + 8*t)

Any idea how to graph it correctly, and why I received the errors?

  • What are the errors you have received? It will also be helpful if you can provide a [reproducible example](http://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example) w/ some sample data & what you have tried thus far. – gung - Reinstate Monica Nov 17 '13 at 20:35

There are two problems with your command:

  1. curve expects the variable to be named x, not t.
  2. The multiplication sign * is missing between (9.8) and x.

Try

curve(200 - (1/2)*(9.8)*x^2 + 8*x)
