You have the general idea with the intercepts and turning points correct for one cycle. I know the software used tricky to master but you must understand the function is a smooth curve. I would use technology to see this.
Apart from the fact it should be a curve the graph (intercepts, maxima etc) are fine. You may notice that the graph is the same as
I know it has to be a curve but I haven't got the software for this so I have to use 'paint'. So what I have posted is correct apart from when I actually do it on paper I draw curves?
Yes - like on this pic (yes I know it says cos(x) but it's the same graph)
