我用mathematica里的solve解带参数的方程,
因为是刚学,英语不过关,所以结果里的东东看不懂,望高手指教一二!
Solve[((X - 2600)/((X^2/60) - 25015) +
X/30)/(1 - (X - 2600)*X/(30*((X^2/60) - 25015))) == (-X/
30 - (X - W)/((X^2/60) -
15))/(1 - (X*(X - W)/(((X^2/60) - 15)*30))), X]
\!\({{X ->
Root[\(-2106000000\) - 1350810000\ W + 810000\ #1 + 9360000\ W\ #1 -
4680000\ #1\^2 + 1498200\ W\ #1\^2 + 1800\ #1\^3 -
2600\ #1\^4 - W\ #1\^4 + #1\^5 &, 1]}, {X ->
Root[\(-2106000000\) - 1350810000\ W + 810000\ #1 + 9360000\ W\ #1 -
4680000\ #1\^2 + 1498200\ W\ #1\^2 + 1800\ #1\^3 -
2600\ #1\^4 - W\ #1\^4 + #1\^5 &, 2]}, {X ->
Root[\(-2106000000\) - 1350810000\ W + 810000\ #1 + 9360000\ W\ #1 -
4680000\ #1\^2 + 1498200\ W\ #1\^2 + 1800\ #1\^3 -
2600\ #1\^4 - W\ #1\^4 + #1\^5 &, 3]}, {X ->
Root[\(-2106000000\) - 1350810000\ W + 810000\ #1 + 9360000\ W\ #1 -
4680000\ #1\^2 + 1498200\ W\ #1\^2 + 1800\ #1\^3 -
2600\ #1\^4 - W\ #1\^4 + #1\^5 &, 4]}, {X ->
Root[\(-2106000000\) - 1350810000\ W + 810000\ #1 + 9360000\ W\ #1 -
4680000\ #1\^2 + 1498200\ W\ #1\^2 + 1800\ #1\^3 -
2600\ #1\^4 - W\ #1\^4 + #1\^5 &, 5]}}\)
#到底是什么意思呀?
还有如何解多个带参数的方程?
