Hey again. Couple more pure maths queries! 1. Show that y=ln(x^2 + 5) can be rewritten as x^2 = e^y - 5 2. The root of the equation sin-1(x) = 0.25x + 1 is A. Show that 0.5 > A > 1 The second...
Hey. I know i asked one yesterday, but this is really tough! Ive done all the rest now, i just need to write down for general solution of: dy/dx = x^2 e^x^3 I know its an odd equation and hopefully...

right. im fairly good with normal distribution stuff, like working out mean, s.d, x, z etc etc... but on this particular question.... its about lifetime of light bulbs. mean = 1700 hours, s.d 150...
Hey Im stuck with a few questions i have been set. Firstly, I need to work out the integration of y = e^x y = e^x/2 y=e^0.5x and y = e^2x Secondly, i need to differentiate 1.) y=ln x^7 / 7 2.) y= e^2x...
hey im really stuck on a integration question for my A level maths course. heres the question, and hope someone can help me out. 4. The curve y=12 - 3x^2 has a tangent at the point p (2,0) on the...
Hey. I have carried out some coursework on breaking stress, and have gathered my results. I need to do 2 graphs on the experiment, and need some idea's, on what to plot etc. thanks
Hello. In my work enviroment, one of my colleagues got one of two needed passwords to access secure data, and he handed it to me. I have never used it, because of the consequences. But if i am caught...
Hey. I carried out an experiement on some wire to find the breaking stress. The result is that the wire is 0.28mm thick, and the force applied until it snapped is 1501.11grams. I know that stress =...
Hey Questions as follow. 1. (a) Given that (2+√7)(4-√7) = a + b√7 , where a and b are integers, find the values of a and b. Im guessing this is simultaneous equations, not sure how...
Hey. Im stuck 'again', i know :/.. Well, any help will be much apprechiated and reped as always. Ill fire away: 1. The points A, B and C have coordinates (1,7) (5,5) and (7,9) respectively. (a) Show...
hello. Im never too sure about how one would go about finding the interception between two linear equations. the question i have is. 1. Find where these two lines intersect : 3x + 4y = 26 and 7x - y =...
