複數根的意思、翻譯和例句

是什麼意思

「複數根」是數學術語,指的是多項式方程的解,可以是實數或複數。在數學中,根是使得多項式等於零的值。當一個方程的根是複數時,這些根通常以形式 a + bi 表示,其中 a 和 b 是實數,i 是虛數單位,滿足 i² = -1。複數根通常出現在二次方程及高次方程中,特別是當方程的判別式小於零時,表示沒有實數解。

1:Complex roots

用法:

指的是多項式方程的解,這些解不僅包含實數部分,還有虛數部分。這些根的形式通常是 a + bi,其中 a 和 b 是實數,i 是虛數單位。當一個方程的判別式小於零時,會出現複數根。

例句及翻譯:

例句 1:

這個方程的複數根是 3 + 4i 和 3 - 4i。

The complex roots of this equation are 3 + 4i and 3 - 4i.

例句 2:

在數學中,複數根通常以共軛對的形式出現。

In mathematics, complex roots often appear in conjugate pairs.

例句 3:

如果一個多項式的判別式小於零,那麼它將有複數根

If the discriminant of a polynomial is less than zero, it will have complex roots.

2:Imaginary roots

用法:

通常指的是方程的根中有虛數部分的解。這些解在實數範疇內是不存在的,通常是由於方程的判別式為負數。

例句及翻譯:

例句 1:

這個多項式的虛根是 2 + 3i 和 2 - 3i。

The imaginary roots of this polynomial are 2 + 3i and 2 - 3i.

例句 2:

當你解一個沒有實數解的方程時,你會得到虛根。

When you solve an equation that has no real solutions, you will get imaginary roots.

例句 3:

虛根在許多數學應用中都是非常重要的。

Imaginary roots are very important in many mathematical applications.

3:Non-real roots

用法:

指的是不在實數範疇內的根,通常是複數根。這些根出現在多項式方程的解中,特別是當判別式為負數時。

例句及翻譯:

例句 1:

這個方程有兩個非實根。

This equation has two non-real roots.

例句 2:

非實根的存在意味著方程在實數範圍內沒有解。

The existence of non-real roots means that the equation has no solutions in the real number range.

例句 3:

在高次方程中,非實根的數量可能會影響解的性質。

In higher degree equations, the number of non-real roots can affect the nature of the solutions.
