can u post the paper or the link to the paper? -
Mathematics: Post your doubts here!
from wat i can gather it will be x^2 + 5x - 8 = 0 where a=1 ; b=5, c=-8 -

ummm no .. the answer is x = (sqrt)3a -

I'm sorry i dont get ur question :`) is it a new question or something from the one that i answered?? -
Mathematics: Post your doubts here!
bcz u have y as lny in the graph and ur x from the graph is x^2 just rearrange the equation in the form of y=mx+c -

NOTE i am considering @ as thita as u found out in part i .. 4Cos@ + 3Sin@ = 5Cos(@-0.6435) 5Cos(@-0.6435) = 2 Cos(@-0.6435) = 2/5 @ = Cos^-1(2/5) + 0.6435 @= 1.8028 radians and 2(pie)-1.8028 = 4.48 radians can't seem to grasp onto the last part tho :P -

rearrange the equation such that it is in the form: lny = lnA - kx^2 --> lny = -kx^2 + lnA from this u can see that ur gradient will be -k and ur y-intercept is lnA find the gradient using the coordinates of the two given points and equate it to -k .... then put in the values of lny , k, and... -

Praise the Lord...! :') EDIT: May I encounter that same feeling very soon... preferably on 13th May too 0:) :P -
Mathematics: Post your doubts here!
yeah i did get the right answer... it was t=100 what i'm asking is that is t=100 the time when the particle reaches B?? shouldn't 100 be the time when the speed is max?? -

Mathematics: Post your doubts here!
the thing that's confusing me here is that after differentiating we get t=100 ... isn't t=100 the time at which the speed is max? in the ms they have considered it to be the the time taken for the distance AB travelled.... it's confusing me to bits!!:/ and umm well solve the rest of the...
