Y_Shun SG Can anyone explain to me the first qtn how to do...do we use the "Radian" mode of the calculator to calculate or what? then for 6<10, how do we do that??
unclebutcher SG use radian mode. sin(whatever)= 3/8 find basic angle. and do the ASTC thingy. i would do it for u...but i have no scanner at home....sry
unclebutcher SG since cot(whatever)=0. (cot (whatever) inverse)=0 inverse thus tan (whatever) = 0 i think. not too sure. let me work it out and get back to u in 5 mins.
Y_Shun SG IOMGS pai seh i put in 1 more bracket which made the qtn more diffcutl ar... the bracket after root 3) should be removed...this is a extra bracket.
unclebutcher SG lemme state that clearer: answer from basic angle and ASTC: A and B(A and T) A+2pi, B+2pi, A+2pi+2pi,B+2pi+2pi so on and so forth till you get your 6<10
Y_Shun SG + 2PI?? whats PI i dun understand the part of 6 how we know how many rounds do we go aroung the ASTC
unclebutcher SG PI is 3.141592654......... you go the required no. of rounds until you get between the values they ask you for, in this case 6<10
eagle SG Don't ask me about chemistry. That one I only know how to calculate num of moles now. Last time to me very easy, now to me is Greek
unclebutcher SG u didnt do chem for a levels did u? if i rmb correctly u did f maths c maths econs and physics... whaha. o level chem chicken feet larh. amaths also. especially trigo equations and proving.
