Differential Equation Test 1 Review
1. Order of a D.E. and Linearity
i.
Order of a D.E. depends on the highest derivative in an equation. E.g. An equation with
first derivative as its highest derivative is a first order D.E
Linearity: A D.E is linear if:

1. The student made a mistake on the fourth step and last step. When adding 5 to both sides the
student did not keep the sign of the number with a larger value. Adding 5 to 11 would be 6
instead of 6. When dividing by a negative n

1. The student didn't put parenthesis between 3x - 2, therefore reversing the signs.
3x + 3h - 2 - (3x - 2) = 3x + 3h - 2 - 3x + 2 = 3h
The correct answer is 3h.
