Extracted text: 2. dv 2cos x-sin" x+y 2. and solve the Exercise 2.7 1. Verify that y1 =sinx is a solution to %3D xp differential equation using the initial condition y(0)=-1 2. Solve the following; y' 3 (1-x)y² +(2x-1)y – x; given solution y = 1 3D1 y' =-y +xy+1; given solution y= x iii) y =-8xy + 4x(4x+1)y – (8x³ +4x² – 1); given soln. y
