Make sure to leave some time to check your answers.

You should make two comparisons when comparing the graphs. First is which is the larger median and the second is the greatest interquartile range, which is how spread the results are.

quick question, for trignometric graphs, do you memorise like how the graphs looks and the values because you cannot use a calculator for sin (180) etc??

do you mean trig values like sin cos tan 30 60 90 etc? the ones u have to know without calc?

theres a way to work them out, which is to use a right angle triangle to work out values for 45, and an equilateral triangle for 60 and 30.

values for 0 and 180 im just remembering them bc theyre just 1 and 0.

if you dont want to work out the values during the test, theres many videos on youtube teaching you easy ways to memorise them

The cosine and sine graphs are okay but tan graphs are confusing to draw. I hope tan does not come up.

do you mean the questions where you have to draw the graphs out or move them?

No not exact values, those are easy to memorise. The trig graphs. Like this
