It is known that the angle MAN=60 degrees, the point B is on the ray AM, and AB=4. P is the moving point on the straight line AN, BP is the regular triangle BPQ (points B, P and Q are arranged clockwise), and O is the outer center of the triangle BPQ.
(1) When point P moves on ray AN, it is proved that point O is on the bisector of angle MAN;
(2) When point P moves on ray AN (point P does not coincide with point A), AO and BP intersect at point C, let AP be X, AC*AO=y, find the resolution function of Y about X, and write the definition domain of the function;
(3) If point D is on the ray AN, AD=2, and the circle 1 is the inscribed circle of triangle ABD, when the side BP or BQ of triangle BPQ is tangent to the circle 1, please write the distance from point A to point O directly.
Khan, I drew this picture myself. Don't take it personally. Dig ha ha ha. This question is actually not difficult. Take your time and get extra points for your answer, hehe.
Give you some suggestions for the senior high school entrance examination.
Most of the senior high school entrance examinations are simple questions (only after personal experience), and the toes of the last question in mathematics can be figured out (Shaoxing volume, the teacher is safe all his life! ), you don't force the storm, just practice thinking.
Go to Baidu to take the "senior high school entrance examination" (post it), and you will have unexpected gains! Print out the good materials in time and review them more! Don't worry, the senior high school entrance examination is much easier than those depressing mock exams!
I wish you good results in the exam! Normal heart!
