The function's domain is [-1,-1/2)U(-1/2,1]
VA @ x=-1/2
HA @ y=+-1
Correct?
Also,
Those two derivatives are y' and y''. My apologies, thanks for correcting.
The function intersects the y-axis at (0,1).
Homework Statement
Y=\frac{\sqrt{1-x^2}}{(2x+1)}
Homework Equations
I took the first derivative which I believe to be:
\frac{(-x-2)}{(2x+1)^2\sqrt{1-x^2}}
I also took the third which I believe to be:
\frac{4x^3+12^2-7}{(2x+1)^3(1-x^2)^(3/2)}
I am trying to find zeros of the...
I have narrowed down my question, specifically to the area I have highlighted on this picture (bear in mind, I can't post pics under 10 posts):

Where did all the dx/dt and dy/dt come from on the right side? I don't understand that step. I know how to...
Homework Statement
s=\sqrt{(3x^2)+(6y^2)}
Homework Equations
None
The Attempt at a Solution
\stackrel{ds}{dt}=\stackrel{d}{dt}\sqrt{(3x^2)+(6y^2)}
\stackrel{3x}{\sqrt{(3x^2)+(6y^2)}}
The problem with that is its only d/dx if y is a set number. I don't know how to...
Thanks for writing that out in latex. I have bookmarked your sig haha.
I will email my teacher. We are doing problems in MathXL and there seems to be some disconnects from what it asks and what the teacher appears to have asked.
If I use L'Hopital's rule then it comes out with the right answer, however, my teacher hasn't covered this rule and I don't think we are supposed to use it.
Homework Statement
Lim (cosθ-√3/2)/(θ-pi/6)
θ→pi/6
Homework Equations
The Attempt at a Solution
My attempt at this has been to try to multiply both the numerator and denominator by either the numerator's or denominator's conjugate. both result in 0 at the denominator.
I also...
