Thank you Hogger for your point outs. Appreciate it. Have a nice day Charles

Thank you for your reply. I wonder which is the correct solution solution (a) ln y = 1/(\psi-1) x ln \psi ln y = ln \psi x (\psi-1) ln y = 1/\psi ln y = 1/1 y = e1 or solution (b) ln y = 1/(\psi-1) x ln \psi ln y = ln \psi / (\psi-1) ln y = 1/\psi ln y = 1/1...

Homework Statement Determine the limit of lim \psi\rightarrow1 of \psi^(1/(\psi-1)) Homework Equations The Attempt at a Solution Let y = \psi^(1/(\psi-1)) ln y = ln \psi^(1/(\psi-1)) lim \psi\rightarrow1 ln y = lim \psi\rightarrow1 of (1/(\psi-1)) (ln \psi)...

Yes I got the other two roots from your guide office_shredder. Really appreciate all the help from you guys. This is a really educative and helpful forum. Thank you so much guys. :)

Thank you office_shredder for your kind reply again. So from y6 = 1. Which also means y =1? Therefore from y = ex 1 = ex ln 1 = x ln e x = 0?

Thank you Office_Shredder for your kind help. I tried to subsitute y=ex and got the quartic equation which unfortunately I am not very familiar with. 9y4 - 9y-4 - 82y3 + 82y-3 + 9y2 - 9y-2 = 0 I didnt know what to do with the negative powers so I mulitplied the equation with y4 to...

Thanks nrqed! Was looking for someone to ask whether if I could do that. Since I can't separate the 4 and the x, what do you reckon I should do for my next step? Or maybe even my first step was wrong?

Oh.. Hahahha! Alright, I guess I am done with Question 1 with the help from you and Office_Shredder. Thank you both again. Would love some help with Question 2 though. :)

xepma I apologise for the confusion that I have caused. Yes I meant (z-i)/(z+1) = 0. After you have pointed out my error, this is what I've got and please let me know if it is the correct way of doing it. [x - (-1/2)]2 + [y-1/2]2 = (-1/2)2 + (1/2)2 As for the radius, if I were to sum...

Thanks for the heads up Office_Shredder Well then I think I should then make my first step by multiplying a conjugate of the denominator (z-i)/(z+1) = 0 [( x2 + x + y2 - y ) + i ( y-x-1)] / x2 + 2x + 1 + y2 = 0 Then i tried completing the squares (with the Real part = 0) to get the...

Homework Statement Question(1) : Find the Cartesian equation of Re[ z - i / z + 1 ] = 0. If the locus is a circle, give its radius and the coordinates of its center. The Attempt at a Solution Workings : So I attempted to solve the problem and my workings are as below ... Since Re = Real...

Yep that was exactly what i got. Fa and Fb as equal and Fc is half of Fa. The deflection measurements are from the dial gauges installed in each member. When they are hung vertically with a load at the bottom, the members tend to stretch and the small amount of stretch is measured as the...

Im doing this problem as a part of the experiment for a Basic Roof Truss. I first started off measuring the deflection for each member of the roof truss (member dismantled from the roof structure) by applying certain amounts of weights. Next I put all the members up into a roof structure as...

Alright the equation Fcd=500=1.96*Fac ==> Fac=500/1.96=255 would be an ideal way to explain my calculation to obtain the weight of A. Thanks again for showing the way Elbarto. Charles

Elbarto, thank you for clearing that up for me. The method you showed me is simpler and clearer than what I've seen. Anyway there's just one more thing, when i get Fcd as 1.96N and i have to scale it to A , so i'll have put it in a ratio wise like Fcd : A ? Since I am going to use this method in...
