let u=e^(sqrt x), integrate e^(sqrt x) w.r.t.x =integrate 2lnu du = 2(u lnu - u) +c = 2e^(sqrt x)[sqrt x - 1] + c hope it is right Now pass on to you Is there a cartesian equation for |z + i| + |z - i| = 1?

What is meant by g force? Does it stand for force of gravity?

i was practising latex

f\left ( x \right )=\frac{ln\left ( x^{2} \right )}{\left | x \right |},x\neq 0. Find (i){f}'\left ( -e \right ) and (ii)\int_{-e}^{-1}f\left ( x \right )dx.

You've got it. I wasn't sure whether you knew what you said.

Ok Please draw a square with all corners on the regular pentagon and find its area. The largest and the smallest?

luv that number, fascinating

why?

my favourite number is 1 because it is written almost the same way in many languages. what is yours?

Here is the answer side = sin108 /sin63 = 1.067395682 area = 1.139333541

Good on you BoF2 a way to find information

gradient = k =-e^(-x) same y-coord =kx = e^(-x) .: -k = kx, x = -1, k = -e

'undefined' means the limit does not exist. 'indeterminable' means the limit may/may not exist.

0<1/(x^2+1)=<1 for all x so -1=<1/(x^2+1)=<1 for all x

luvu im bos without bof2

Leave him alone as long as no obscenity is used. He keeps coming back because he likes here. He makes fun read for some ppl. If you don't like it, don't respond.

Love this site Unlike others, here you can work/learn or play, you meet funny and serious ppl, a big melting pot

Question If the person walks towards the lamp, at what speed does the length change at the moment the person is directly under the lamp?

sorry read the question wrong. 1.5 m/s is the speed of the end. so the speed the length is increasing is 1.5-1=0.5 m/s
