yes, I have no idea how to do (a) but for b I tried substituting 1 and solve for y. I don't know if it is right
I am really confused when it asks for the slope
PLease help if you can!
Thank you so much
P.S. You don't have to provide me with a solution, just some hint or help would be...
Difficult gradient problem!
Consider the curve with equation x2 + xy + y2 = 3.
(a) Find in terms of k, the gradient of the curve at the point (−1, k).
(b) Given that the tangent to the curve is parallel to the x-axis at this point, find the
value of k.

Hey
I recently did an experiment on the absorption of gamma rays
I calculated the thickness and the no. of counts, got a nice exponential curve.
So, I used lead as the absorbent or shielding material for gamma...
Any suggestions what else I can use for gamma?
I thought about sausages or...

OK, so I did this experiment a week ago,
I took 75g of juice and added some 1.5gKI, 7.5cm^3HCl and 5cm^3starch and titrated with Potassium Iodate 0.010M(KIO3). I did this titration again
For the third experiment, I just took 0.1g pure C-vitamin dissolved in some water...
Parabola or an ellipse??
Homework Statement
I have a curved structure which looks like this:
http://imageupload.org/pt-1412920046522.html
I haven't been told specifically what it is.
I assumed it to be ½ellipse. It has a height of 36m. So, I also found out the equation y=...
Cool, so that would just be x+y+z= 18, i can't download autograph (the only best 3d graphing software). I am super curious about how the graph of this might look like. Any ideas about the software?
That is a really in depth explanation and sounds difficult too. I actually wanted to keep it...
Are a and b both 36? Also, I am having a really hard time differentiating it with respect to L.
Wondering if you can elaborate?? AND isn't it also supposed to be a cuboid??
Thank you so much for helping!
that method is really complex, i mean is there any other way rather than using 3d graphs?
Like, differentiating or something
also, isn't the local maximum just (0,36)
Thank you so much for helping me!
I have a upside down looking curve structure (½ ellipse). It has the following specifications:
The building has a rectangular base 150m long and 72m wide. The max height of the structure should not exceed 75% of its width or be less than half the width. And the min. height of a room in the...

Differentiating an equation!
Homework Statement
How do I differentiate this
V(x) = 300x * sqrt(1296-x^2)
The Attempt at a Solution
I tried using the product rule but that didnt work at all
PLease help
Thank you so much!
It could be anything, but I decided it to be an ellipse
So,
(x^2/a^2)+(y^2/b^2) = 1 is the equation
and then would a and b be both 36? if I want the height to be 36m??
So, the equation is
x^2+y^2=1296
So when graphing, would the equation be just y= sqrt (1296-x^2)?
That gived a...
