There are five questions in this assignment. Answer all the questions.
Question 1: (i) Find the complex conjugate of (3+5i)/(1+2i)
Here
z = (3 + 5i)(1 + 2i)
= 3 + 6i + 5i + 10(i x i)
= 3 + 11i – 10
= - 7 + 11i
Then Complex conjugate of – 7 + 11i
= - 7 – 11i
(ii) Differentiate (sin x)x w.r.t. x.
(iii) Find all the seventh roots of (3+4i). (5 Marks)
