بكلتا i need clear ans by hand and solve ery very fast in 20 min and thank yOL | DYBALA solve it. (x,y) = xy an integrating factor for the following differential equation? If so, (2y cos y) dx + (2x cos y - xy sin y)dy = 0 ng factor for the solve it. dx+(2x cos y-xy y)dy = 0 Crential cause

40 Complete the following exercises in complex arithmetic. a. Find the complex conjugate of (4 +j4), (2 –78), (-5+j2). b. Convert the following to polar form by multiplying the numerator and denominator by the complex conjugate of the denominator and then performing the cpnversion to polar coordinates: 1+l j4 4+j4 2- 8 -5+j2 c. Repeat part b but this time convert to polar coordinates before performing the division.
