you shall be able to get the acceleration and so you can get the force and you can find the final velocity where the initial velocity is 0, then you know that P=FV, and its done. it's very simple.
regarding permittiivity tis might help.(http://www.radio-electronics.com/info/formulae/capacitors/permittivity.php ),
the other terms you can get them from physics 102 course textbook.
an Improper integral
you have to Divide the integral into two
the first is from -∞ to 0 & the second is from 0 till ∞ and
HINT: this is an improper integral, consider taking the limit
for example limC goes to -∞ (of your integral)
lim D goes to ∞ (of your integral).
and continue.:smile:
i started it three times with the mean value theorem (roll's, general mean value theorem,& integral mean value theorem), how ever, it didn't work so if you were in my case what will be your way of solving this question!
for joen how can u make through contradicion give an example, and for SiddharthM the critical point for g'(x) is f'(x) and through the first derivative test it can be proved i imagined that if you can solve the first part so you will do it in the second part but i don't know how.
thanks for interesiting i solved it and the answer is (0 , 1.25). first i solved for the equation of a circle and then i got another equation which is ( the tangent * thenormal=-1)
whith a lot of my friend's help.
thanks again
hey why did you move that.,please replace it as its first condition, because first it is not a home work, second the circle equation is
((x^2)-x)+((y^2) - y)= R^2
