(b) (c) By using the substitution z = can be reduce to cos y, show that the differential equation dy cot y dx (ii) dz dx (1) Show that the equation is an exact equation. NX 3x Hence, solve the original equation when y(1) = 0. CSC y -e³x. (3x²y² -10xy²2)dx + (2x³y-10x²y)dy = 0 (10 marks) (3 marks) Then, determine the general solution from the given differential equation. (7 marks)
