hey desperate help required!
usually for graphs i don't usually know how t set my scale up.
like this question on may/june 2008 31,my values for cos(Q/2) were from 0.79 to 0.87,six of them and they had to be plotted on the y axis.if i start from 0 and go on like 0.1,0.2,0.3... then its like i have wasted half my space and then my graph is right at the top,the examiners want us to use 3/4 of the spce available,so im not sure if im right or not.
