Name: Solve: 1. (5(cos vx))- (A) -5 cosxsin 2. (C) -10 sin (+) x+2x +3x+7 ax Grade: (B)-10 cosx sinx 5 sinx (D) (A)x-3x+7+(5)3x+6x+ (C) =+c x+4x+7x 3. Ms. Collagebored attempts to solve the differential equation 2x(2 y) with the initial condition 1 when x 3. Her steps are shown below. In which of the following steps does the first error that y ? Step 1: dy 2xda (2-y) Step 2: In|2y|=110 Step 3: 9C so In|2y|= x 9 Step 4: y (A) Step 1 (B) Step 2 (C) Step 3 (D) Step 4
