WebComplex numbers can often remove the need to work in terms of angle and allow us to work purely in complex numbers. For example if we have an orientation, represented by a complex number c1, and we wish to apply an additional rotation c2, then we can combine these rotations by multiplying these complex numbers giving a new orientation: c1*c2. Web21 mrt. 2024 · Given two complex numbers. The task is to multiply and divide them. Multiplication of complex number: In Python complex numbers can be multiplied using * operator. Examples: Input: 2+3i, 4+5i Output: Multiplication is : (-7+22j) Input: 2+3i, 1+2i Output: Multiplication is : (-4+7j) Python3. def mulComplex ( z1, z2): return z1*z2.
