For the first SS, it's all correct besides the third one (letter b). Just need help with letter b. As far as the 2nd picture, I just need help with the last question (letter c)

Solve the initial value problem if = (a: + y 4]2 with y(0] = 0. a. To solve this, we should use the substitution help (fonnulas) help (Formulas) Enter derivatives usmg prime notatlon (e.g., 1you would enter 3;\" for i). b. After the substitution from the previous part, we obtain the following differential equation in 3,411., u'. u=tan(x+ c) i, A help (equations) e. The solution to the original initial value problem is described by the Following equation in 1:, y. y=tan(x+ tan_1 (4)) +4xy'. help (equations) Solve the initial value problem yy'+ z = 1/32 + 3,.2 with y{2) : m. a. To solve this, we should use the substitution 1],: help (formulas) u': help (formulas) Enter derivatives using prime notation (e.g., you would enter 3," for g). b. After the substitution from the previous part, we obtain the following linear dierential equation in 3:, u, u'. c. The solution to the original initial value problem is described by the following equation in any
