    Thanks for correction..I didn't realise log of negative values don't exist...Well...the only u need to keep in mind is that, whichever value that makes f(x) zero can be the value of x...!! -2 was given in question..so i didnot think anything else..!! my apologies..m sorry

    My teacher once told me about it, but i think i forget...I think this is what he told me. The experiment is done within a population and then sample is taken..so u have to divide it that way....If sample is taken and find out mean and all..u dont need to do that way....actually, i think this...

    Well, u have found out w and w^2...so..plot it in a graph..i assume, its not difficult for u to plot in a graph..then join those two points. Now, the line u can see is a diameter of a circle. so u can put a ruler to find out a length..and divide it into two half...the pt which divides the line...

    {3^y}^3=27^y, {3^y}^2=9^y .....So if u compare the f(x) and equation in (ii), its the same... if u substitute the value of x as 3^y in f(x), u will get the same equation shown in (ii)... So, do this way.. Given equation:12*27^y+25*9^y-4*3^y-12=0 or, 12* {3^y}^3 + 25* {3^y}^2 - 4* 3^y -...

    For calculation, u can use distance formula...from origin to U....u may have some pt..it its 2+3i, the co ordinate is (2,3) so...u can calculate the distance i hope...and that distance- radius of a circle gives u a least distance...hope that helped..here's a figure for little more help..:D

    I assume you did iii)...U should have made a circle with radius 1 and centre at u...what u may be, i hope u have calculated earlier. The point u need to recall is, z is a point anywhere at the circumference of that circle. and calculating |Z| means...calculate the distance from origin to the...

    Q1) y=sqrt(4x) and find dy/dx. dy/dx gives the slope of the curve which is also the same for the tangent. So, the slope of tangent is 2(comparing y=2x+c with y=mx+c) so, dy/dx=2 ...and solve it to get the value of x. After u get the value of x, put it in the curve's equation to get the value of...
