does any have any idea how to solve for x. the only thing i can think of is taking the natural log of both sides, but from then i get stuck thanks i know that two solutions are 2 and 4 but i cant work out the third one

i think Ryde might be too far i think ill try the abc shops thanks for the help people

i didnt really know where to put this question, anyway, does anyone know where i can buy the fronline episodes required for hsc english, any shops.. whatever. thanks

the potential diiference is produced when the zinc anode oxidises to form Zn2+, these ions then go into solution, the electrons travel along the external circuit where the ions in that half cell collect the electrons and adhere to the cathode, the site of reduction. i think you need to write...

i see now, thanks a bunch

given In = (from 0 to pi/2) cos^n(x)dx prove that In = ((n-1)/n)In-2 i know we have to use IBP, but i cant seem to get the In-2 any help thanks

try using a substitution of u=16-x

make the top, x-1+8, then just divide, to get 1+[8/(x-1)] then integrate to get x + 8ln(x-1), then put the the numbers in same thing for the secong part.

does anyone know the mission/vision statement for qantas, ive looked for ages and cant seem to find anything any help thanks

hello everyone, weve got an assessment coming up soon, and it involves all the economic issues. i just wanted to know if the howard gov. considers external stability as an objective. obviously in our textbooks, the authors explain the policies that can reduce the severity of external...

for the integral try changing it into part sec^2(x) - 1 and part tan^2(x) then try and use a substitution

for the first one, let d/dx(1/2(v^2)) = a = 8x(x^2+1) integrate a to get the value of 1/2 (v^2), then simplify to get v by itself

has anyone noticed that in fitzpatricks 33(a), questions 22 and 27 are exactly the same? strange thing is, there presented in the back as having different answers

i think you guys will find that the questions are not at all wrong but just in a different form. see, your answers involve cos^3x, while the answers in the back have cos3x. if you want to check, try expanding cos3x, then from the expansion make cos^3x the subject, and sub it into the answer you...

did you mean + c

try changing cos2x to 1 - 2sin^2x, then simplify the integrand to get sinx - 2 sin^3x then using the expansion of sin3@, make sin^3@ the subject and place this in your simplified integrand. it should be simple from there.

you make it sound so easy, thanks!!!!!!!!

im having trouble with this question: a particle moves in a straight line, and at time t, its displacement from a fixed origin is x. if x(dot) = x + 3 , express x(double dot) in terms of x ans: x+3 thanks for any help

thanks for the help guys

??????? the answer is supposed to be ln(1+rt2)
