well for 7)b)iv) i had 0.16 for 0.8<m<1.2 but i dont think that cant be right..because in that range for m, m can equal 1, which means theta is pi/4, which is the maximum range... and so after that it reduces again...which mean the maximum distance is m=1 and the minimum would be eitherwhen m is...

i really thoguht it wasn';t that bad, even question 10, more time consuming than hard...but i made really stupid errors, so yeah...the easy marks are gone

yeah...i didn't find the test hard, rather really time consuming, although i did manage to finish but ive made some really stupid mistakes so easy marks gone down the drain.

yeah...i got that too..wel unti lthe last step....and i jsut realised i subed the 2 2/3 in to the wrong equation..as in jsut withotu the two on th bottom so i got 112.something
