Okay, so I've found this geometry question that's making me crazy (because I'm really weak in geometry, sighs)

Could you help me? c:

The question is as it follows:

take the segment AB with a lenght 6. Consider a semicircle with AB as the diameter. Let P be a point on the arc AB. Let x = <ABP.

1) express the area of the triangle ABP in terms of X.

2) find the range of x for which the are of the triangle

3) if the point P is so chosen that PA + PB = holds, find the area of the triangle ABP.

I don't know how to find the area in terms of X, but with this area found, I think I can manage the other questions.

Thank you c:

Sorry for bothering you with such a silly question!

Thank you very much for helping me! c:

hello! so, I've came accross a problem I can't solve at all :c. The problem is as it follows:

**The constant term of **

I searched how to solve it and found only one solution, but I didn't understand what was done... they turned

into and somehow found that k = 2. also, they found "", which give us a = -3.That's actually the right answer, but I can't figure out what was done to solve this problem... :c Can you guys explain it to me?

Thanks c:
