一條數學

-終場ソ使者-

最快捷既方法係calculus- -

無．話可說

但係calculus你都要自己define d equation
then又要find intersection
之後又definite integral
都係好煩

Set a system of linear equations
A + 4B + 4C = 100
A + 2B         = 50pi- 100
        B + 2C = 100 - 25pi
Then, solve it !!

determinant = 0
singular matrix
no unique solution.......(3) is a linear combination of (1) and (2)
