Ok, I was going out with this chick for a few weeks, she decided to break up with me cause she thought she loved her ex. I was heart broken, but I got over it and her a couple days later. But I still loved her. The next day her and her friend called me and told me that she didn’t love her ex, she loved me, and she asked me out again, I said yes. About a week later she broke up with me cause her mom didn’t want us to date. I was again heart broken, but still loved her. I haven’t been able to talk to her cause of certain reasons, but she talked to my sister the other day and told her that she missed me and wanted me back. I don’t want to get hurt again, but I miss her and I love her.

Circle, 12 feet diameter.
Pins sticking out of the circle, 0.3 inches.
Imagine the the chord line as secure base for the pins (Therefore pins are longer towards the middle but still only protrude 0.3").
The pins can vary to a maximum of 3.5 degrees off tangent.
What is the widest chord possible given the above?
If all the pins were tangental, the pins could not be withdrawn inwards from the circle. This is the key part, the pins which are attached to the chord must be able to move inwards, hence using the 3.5 degree allowance to keep the pins at 90 degrees to chord.

you have two angles and one side of a triangle. the angles are on the two ends of the known side, what's the best way to find the lengths of the other two sides?
it seams like with the two know angles and a known side (and in the same place) it should be simpler (more simple) than what I am finding by searching. is there a better way when it is set up like this?

tangent to angle: "what's your "sine"?"

Let (P_n) be a sequence of polynomials with real coefficients for which there exists a positive integer m such that degree(P_n) <= m for every n. Show that, if (P_n) converges for m +1 pairwise distinct elements of R, then (P_n) converges on R to a polynomial P. (Hint: Consider Lagrange Interpolation Formula)

Show that this conclusion may fail if the sequence (degree(P_n)) is unbounded.
