Help me its a differential equation problem

1. Use Euler's method with three steps to estimate y(2), where y(x) is the solution of the initial value problem =y - ? , y ( 1 ) = 0. Show all calculations and present the values of En ,yn and the slope Pn = f(In, yn), as simple fractions, in a table. Do NOT use a CAS! slope Pn = f(In, Un) 2. For each of the following differential equations, determine whether it is an exact equation or not. If it is, find a general solution. a. 2yeary dx + ((2xy + 1)e2xy + 2y) dy = 0 b. (xy2 - 493) dx + (x2y - 12x2y) dy = 0 2 - 2y 3. Consider the differential equation 2 dx x - y (a) Rewrite this equation in an exact form and verify that you get an exact equation. (b) Solve the initial value problem y(1) = 2. You may leave the answer in an implicit form
