Hello Readers It is quite interesting to write about sets. I found that beginners face a lot of doubts to find out whether given collection of elements forms a set or not? To delete their doubts from memory, I have explained this concept with lots of examples. SET: Set is a collection of well-defined … Continue reading Sets(very easy approach)

# Sum and Product of Complex roots of Equation z^n = z_0

Hello readers, This post is related to calculate sum and product of roots of an equation in the complex variable z^n = z_0 where z_0 is given the complex number. You can refer to the following link to study how to calculate powers of complex number and roots of the complex variable equation z^n = … Continue reading Sum and Product of Complex roots of Equation z^n = z_0

# Powers and Roots of Complex numbers

Hello Readers My today's post is related to find the nth power and nth root of a given complex number. Power of a complex number: Given a complex number z=x+iy, the problem is to find the nth power of z. To answer it, one can use the powerful tool ``Demovire's theorem". For a given z=x+iy, … Continue reading Powers and Roots of Complex numbers
