ive done my half yearly well i wouldn't call it an half yearly just a normal assessment. It was just on Curve sketching and polynominals Didn't go as well i hoped...i kind of went blank in the test. gotta learn from my mistakes. =/

i got tutor for chem, physics, 3unit, 4unit althogether it cost 70

Log base e same as In easy for me to look at well... In(5/2e) using log laws... In5 - (In2 +Ine) 1.62-(.69+1) not sure..

i do all the subjects except for bio tried a study group on the net.... well you can say that it failed for me and my friends =/ once someone mentioned utopia! or wc! or sc! well we get abit off track meaning we all went off with big heads and started a tournment against each other. I won of...

dw about the q finally did it =/

(e^x2) <--- thats x^2 e^u=u'e^u 2xe^x2<--- thats x^2 not sure about that. and for the others...can't think right now ill try to do it later..

for 2unit i was comming in the middle of the grade 20th and for 3unit was also in the middle. all i did in yr 11 was play games =/ currently in yr 12 started paying attention more in tutor and school, also doing all my hw, now comming first/second/third in 2unit and 3unit...just hope i can keep...

i hate geometry but for the rest its straight forward for me

My teacher at only likes the fitzpatrick text for both 3unit and 2unit. but we get our notes from the maths in focus. though i like working off cambrigde for own study

sorry another q a) area bounded by y=inx,the x-axis and the lines x=2,4 using simpson rule. b)Change subject of y=inx to x c)Hence find exact area in part a) Don't need to do (a) and (b) just (c) well heres what i did ans for a)2.16 b)x=e^y c)Interration of e^y dy= [e^y] values are from...

knew i was right =D oh and dw about the other q stupid me too much studying i guess and no rest thanks i'll be back with 4unit q next time =D

Another question further on from the question before Use the simpson rule with 5 function values to find the volume of the solid formed when the curve y=e^x is rotated about the y-axis from y=3 to y=5. Answer is 12units^3 And another y=INx change subject to x

thanks da monsta didn't expect an answer that quick =D got a 3unit test soon on logs exp and trig funny how we are doing 2unit topics in the 3unit exam

Got equation y=e^ 2x or y=e^x how do you make x the subject? thanks

thanks for the replies now i understand though my school sucks -_-
