can someone tell me how to graph this equation on my graphing calculator: 300(2+sin(4sqrt x+0.15)) for 0<x<20
You can get quite detailed information by Googling your calculator model and graphing.
I found the following link on uTube but haven't seen it because I don't have flash installed on my computer.
Give it a try if you have a Ti83 or Ti84.
