yeah I know it, I said I did it that way. But the problem is that nothing is told about it. Anyway thnaks, I think the question wasn't complete in this case
that's because of this.
suppose that a=x+y and b=xy then
\sqrt (a + 2\sqrt b) = \sqrt x+ \sqrt y
Ivy, I don't get what you mean. How do you know if the numbers x and y are rational then the only solution is x=y=0.5? and how do you know there is an infinite number of solutions if they...
can't get this!!!
Hi there,
I have a question that I cannot solve. Here it is.
\frac{1}{\sqrt(4-2\sqrt3)}=x+y\sqrt3
then what is x^2+y^2?
All I did was finding what left hand side stood for. It equals
\frac{\sqrt3 + 1}{2}
Any help?
Well thanks but I just introduced myself to the integral calculus so I do not understand anything from what you say.
edit: btw graphing doesn't count it is too easy using the graph
\int_a^b (x-x^2)dx
What values of a and b make this integral's value maximum? I have tried to do it but cannot get it. I know that the maximum value of x-x^2 is 0,25. but I'm stuck from there.
I try to write the integral in the form of a riemann sum but (b-a)s cancel each other.what am I to...

My method is new (is the first method to calculate pi(x) involving an integral and not a sum) so i think is worth publishing,the problem perhaps is that i am not famous and can not compete with these snobish teachers of important universities publishing nonsenses and useless things , sorry i...
I never thought that way but it is not needed. It's like the lines that are in theradar screens. I looked at your diagram, but the process is, I think, like building a circle by using a line segment and revolving it around a point. The two are similar.
We use the point's place on the line to...
As far as I am concerned, we use the point's place on the line that revolves around the pole. I have shown the proportionality thus.
You said that the line can intersect the spiral at most 3 times. I don't understand this because I think it is at most 1. That is because the spiral is made up...
