大學(xué)數(shù)學(xué)題求教!
是英語原題,試著翻譯過來：
1:
給出線段a,b,c,構(gòu)建ax+b=c的根.記得方程式的根等于方程式的解；幾何上來說,這是個(gè)平面和x軸的相交部分.
Construct the root of ax+b=c,given line segments a,b,c.Recall the root of an equation is the solution to the equation; geometrically,it is the intersection of the graph and the x-axis.
2:
證明兩個(gè)投射面的連通和是克萊恩瓶.
Show that the connected sum of two projective planes is the Klein bottle.
