Ｓ ------- dx
x^2+9
2)
4x
S ----- dx
x^2+9
3)
4x^2
S ------dx
x^2+9
4)
x
find S lim + (sin x)
x-->0
=>lim + ln sin x
x--->0 -------- 後面就不懂了
e 1
-----
x
5)
sin x
S S ------ dA
R x
where R is the triangle in xy plane bounded by
the x axis , the line y=x , and line x = 1
6)
find the minimum value of the function
f(x,y,z) = 2x^2 + y^2 + 3z^2
subject to 2x-3y-4z =49
算出來x=3, y=-9 , z=-4
請問後面是直接帶回去f嗎？？
請大大幫忙指點 一題也可以
我知道我很弱 orz
