Thanks, i tried subtracting c from b and i got the correct answer! It wasn't the sign of a, i had just simply got the signs wrong, but you pushed me in the right direction. Seems very simple now!

In the previous comment, i assumed ax^2+bx+cx=0 since that's the form of my equation. If i calculate, by transforming my equation to ax^2+bx+c=0 by adding both a and b together (because they both have one x) and making it b, and then making c = 0, i get x=0 (promising) but then x=-6.459 which is...

Okay, so where we have a =(0.5*9.81)/(Vx^2) = 0.2929 b =Vy/Vx = 1.19175 c=TAN(35) in degrees Plugging it all in and checking with calculator and excel, i get x=-0.7119 and x=-3.3568 Neither of which are the intersection. Also, it is not referring to t or time, because the time range is only...

Its not a quadratic equation because it can't be put into the form of ax^2+bx+c=0 since we have an x on both b and c, so what i have is ax^2+bx+cx=0.

i use solidworks, and most companies are starting to now as well. The add ons are really usefull, you can basically simulate everything in the real world, any movements, gears etc including friction, torque required etc, and flow simulation, and heat, stress etc. Its almost like an...

I have the following equation which describes a water jets trajectory. Vx=Cos(50) * 6.5m/s Vy=Sin(50) * 6.5m/s x=Vx*t y=Vy*t-0.5*g*t^2 where t=time Now, this plots a curve very well starting from zero. I want a line, starting from 0 also, that intersects the curve. Now, I have...

thanks for the concern buddha

i posted this question over a year ago, so why do you think I am still looking for an answer? For the record, from what i can remember, this was revision help. No point getting all angry because people haven't 'made a reasonable attempt'. I will just take my questions onto yahoo answers where...

Is no one answering my question because they don't understand what I am asking? Or have i not provided enough information? Any help is appreciated. thank you

Here is the problem i am trying to solve; A power-law fluid has a density of 1075 kg/m3. It is pumped at a rate of 2500 kg/hour through a pipe of internal diameter 25 mm.The flow is laminar and the power law constants are K2 = 3 Pa.s^n and n = 0.5. Estimate the pressure drop over a 10 m...

oh i see it now... knew it would be right infront of me!

please explain ?

Hello Im having some trouble making BETA the subject (thats the B) I have scanned in my problem and posted it below. Last time i did something similar to this, it was obviously and right infront of me, so let's hope its as easy this time. Thanks...

How do you rate your TI-NSPIRE? worth the money?>

I have the Ti-NSPIRE, very expensive, has a colour visual screen with a touch pad. Will do absolutely everything and anything you tell it to do. Its just whether or not you can justify spending that amount on a calculator. When you look at it, its only 30 or 40 quid more than your standard...
