OO O 2 01 O 1/2Question 10 Transform the equation rydx - (x + 2) dy = 0 into the form of a variable separable f(x) dx + g(y) dy = 0 adr dy = 0 adr ydy = 0 O (z +2)dr dy = 0 U O du =0\fQuestion 12 What is the general solution of cydx - (x2 + 3y) dy = 0 ? O x2 + 6y? Iny = Cy Or2 - 6ylny = cy O 12 - by- Iny = C O 12 - 6y? Iny = cyQuestion 13 sin rainy da + cos rcosydy = 0 is a variable separable differential equation . O FALSE TRUE\f\fQuestion 2 What is the degree of f (x, y) = 5r -y OO O2 O -1 01Question 3 Which of the following represents the particular solution of the differential equation of ryy' = 1 ty whenz = landy = 0 ? Ox+ y = 1 Oy = 12 + 1 Ox - 12 = 1 Oy= z - 1\fQuestion 6 What is the degree of tan 3y O 1/2 O0 O 2 O 1Question 7 What is the general solution of of the differential equation y = ysecr ? Oy = c(secr - tanz) O y (secr + tan x) = C O y (sec x - tanz ) = C Oy = c(secr + tanz )\fQuestion 9 What is the general solution of of the differential equation y' = ry ? Oy (x + C) +2 =0 Oy (2 2 - C) +2 = 0 Oy(23 + C) +2 =0 Oy (22 + C) +2 = 0
