好易wor
成個cyclic quad.係度

唔使多D, E 2 點都計到...

join PQ

ABC + ACB = 130
XPQ + YPQ = 360 - 130 = 230
XPY = 360 - 230 = 130 (ans)

同我個方法原理其實一樣
只不過我見到幅圖就反射性用ext. angle of cyclic quad.

初頭看不明D, E係乜野~~

circle黎黎去去都係o個幾隻
好過trigo 3d連題目問邊隻角都未知...

3D易d啵...一係cosine law,一係sine law...

問邊隻角都未知, sine/cosine law只係紙上談兵

我覺得圓既LQ好難~
但係我d同學(有修AM)話好易~

A.Maths圓D LQ會問勁多tangent,family of circles,
touching of two circles...仲成日加埋locus來考,都唔係人做既...

Maths圓少好多

我冇修都覺得ok

Maths真係比較少問圓

我自己覺得Maths最難係3D

最淺係或然率

一定啦, 乘乘乘加加加就得,
但如果頭腦唔清醒o個日就好難講lu

仲有甚麼bisection, 自己作左個program入部3650
禁禁禁, 出晒D答案, 勁爽

3d o個D我真係收得, 尤其係a. maths

amaths 圓真係難, 但純locus 就好易

我成日畫錯D線, 係mock度waste左我15min
好唔想做, 但又冇理由做trigo 3D

手計白痴地錯左
