hey... dan, i did what u said and it brought me back to where i started... the biquadratic ur method gave me was the exact same as the biquadratic method i came up with... 24.01t^4 - 729316t^2 + 2251600 = 0 ... however... i used ur way of finding the angle (subbing t int 40 = 854sin...) and...

ok... ill try what u said Dan... thnx a lot for your help. ill post again if anything comes up. - Tu

hi... I am sure all u guys have heard of the sniper question my fellow classmates have posted... but for some reason my method is not working out... i am off by a very miniscule amount which i cannot seem to find out why... any ways this is what i came up with Scenario: you are 1500m away...

u have accel, v1, and distance use (v2)^2= (v1)^2 + 2ad

omg... that's why it wasnt working... i was like so clueless... forgot bout that... thnx a lot man. i c what u meant when u were talking bout e^x now... thnx, very much appreciated for putting up with me.

ok.. but i still don't get how i would solve for x if i had logx^18 = logx^18... wouldn't i just end up with 0 = 0?

yea i know exp(x)

srry.. but i don't think we learned e^x

oo... ok... so now that i have that... how do i solve for x in a though?

hi guys, I am not too sure how to do these questions: solve for x, a) (logx^3)^2 = logx^18 b) logx^3 + log(x^logx) = -2 so this is what i got so far: a) (3logx)^2 = logx^18 9logx^2 = logx^18 18logx = logx^18 logx^18 = logx^18 ... then i got stuck... i was clueless and...

hi guys just want to clarify something... If we are givin (vectors w u and v) w=au +bv what can we say about w a) if u and v are independant? b) if u an v are dependant? this is what i got so far. a) w cannot be writtin as a scalar multiple of u and v and are therefore not coplanar...

alright kool... thnx alot - Tu

yea i get what u are saying. so if up is positive in the diagram then the Fnet since it is slowing down(moving up in this case) will also change to positive?... so if i left it the way it was where Fg was positive would this wouldn't be wrong would it? Fnet = Fg - Fr Fr = -Fnet + Fg =...

Hi guys… there was a lot of arguing in my class when my teacher gave us this one assignment question that I’m not too sure about. It goes as follows… A Polar Lander somewhere above the surface of the Mars is landing with a deceleration of 23m/s^2. If the Lander itself had a mass of...

lol... I am writing it too... April 19 right?... I am only in grade 11 but i jumped ahead in math so my teacher let me write it. i hear whoever gets first place in it gets a really good scollership for waterloo.
