f.2主項變換!星期1要交。急!!!!

2009-09-26 1:34 am
y/3x=2/y+1/4x

p(m+n)=T-qm-qn

點做!

有f.2主項變換的E.G就更好

✔ 最佳答案
y/3x=2/y+1/4x [x]
y/3x = (8x+y)/4xy
4xy^2 = x(24x+3y)
4y^2 = 24x+3y
24x+3y = 4y^2
24x = 4y^2-3y
x = (4y^2-3y)/24 //

p(m+n)=T-qm-qn [m]
p(m+n) = T-q(m-n)
pm+pn = T-qm-qn-pn
pm=qm = T-qn-pn
m(p+q) = T-qn-pn
m = [T-n(q+p)]/(p+q) //

y/3x=2/y+1/4x [?]

p(m+n)=T-qm-qn [?]

主項係...?
