Anyone else getting Latex errors here?
Part circle(radius is "r" ) is made from a string.string's lenght is "L".so the part
circle's circumference is also "L".If part circle's area is "A",Find the angle of the part
circle when Area is maximum
,here what I did but never got the answer.what is wrong in this?
setting to zero for the maximum value
now what? answer has to be r(L-2r)/2(as books says).

[can any admin or mod help me with this Latex error please ]
Use [tex] instead of [tex]
How did you come to the Equation in A the second time?
I get:
Also, you did the differentiation wrongly as L is a function of r and has to be considered in the differentiation process.
When you have substituted correctly x into A, you get the relationship between A and L. That seems what your book was looking for.
Strange... there weren't any posts when I checked this thread and suddenly, there are 6 posts before my first post here
Anyway, Show me how you got your second equation for A. You did a mistake in the substitution of x.
