Calculate the difference 1/(5+2i) – 1/(5-2i) .
Let z = 1/(5+2i) – 1/(5-2i) First le will determine common denominator. (5+2i)(5-2i) = 25 + 4 = 29 ==> z = [(5-2i) – (5+2i)]/29 = (5-2i-5-2i)/29 = -4i/29 ==> z = -(4/29) i

Determine the image of the function y=x/(3x^2+2)
y= x/(3x^2 + 2) Cross multiply: => y*(3x^2 + 2) = x ==> 3yx^2 + 2y – x = 0 ==> (3y)x^2 – x + 2y = 0 ==> x1 = [1 + sqrt(1-4*3y*2y)]/2*3y = [1+ sqrt(1-24y^2)]/6y We notice…
