4. a) Given that z = 2 – 3i, express i'z, and Z/Z* and Z (cos - isin -) in the form a + bi, where a and b are real. Z+1 b) Given that i, find z in the forms a + bi, where a and b are real. Z-1 c) Given that the complex number 2i represents the point A on the Argand diagram and that the point B represents the image of A when reflected in the line y = 2x, find the complex number which represents the point B.

Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
