You should be able to solve a differential equation that is/can be solved by: ⚫ separable ⚫ linear ⚫ exact ⚫ a substitution (homogenous, Bernoulli's or Ax + By + c) Practice Problems Solve the following differential equations 1.(y²+1)dx = y sec² xdy dy 2. x(x+1)+xy = 1; y(e) = 1 dx 3. dy - y = e² y² 4. (x + y³)dx + 3xy² dy = 0 dy 5. + 2y = 1; y(0) = dt 6.(y²+yx)dx+x² dy = 0 - dy 2xy) = dx =y(y+ sin x); y(0) = 1 7. ( + cos x 1+y2 1-x-y 8. = dx x+4 dy dx 9. (x² - 1) + 2y = (x + 1)²
