The paper was awesome, i'm sure i got 74/75 wat im not sure of is the g inverse(3) the very last question, i got the write answer but its not write answer within the range of the inversers function so i got 0.34 rad, but i'm thinking it should have been 2.8 rad since this is in the range of b/w pi/2 and 1.5pi. wat do u guys think? will i loose a mark or will i get 75/75???
