(Review of Complex Numbers) The three most important facts to know about complex numbers are that • i² = -1 ⚫ every complex number can be written in the form a + bi, where a and b are real numbers ⚫eit = cos(t) + i sin(t) (this is known as Euler's formula) When manipulating complex numbers, you are free to always treat i as you would with normal algebra (in terms of factoring, rearranging, etc.). If you ever have an i², you can replace it with -1. To divide complex numbers, you can multiply a fraction's numerator and denominator by the complex conjugate of the denominator, and then simplify: a+bi = abic di c+ di c+ di c - di =... You should be able to rearrange it to something of the form A + Bi, where A and B are real numbers. Write each of the following numbers in the form a + bi, where a and b are real numbers. (c) iii2-i+1 (d) eлi
