   He didn't understand the concept of differential equations.

   Differential equations are equations involving derivatives.

   This differential equation can be easily solved by Laplace transform.

2. sự chênh lệch

   A qualitative or quantitative difference between similar or comparable things.

3. cuộn dây vi sai

5. vi phân

   A quantity representing an infinitesimal change in a variable, now only used as a heuristic aid except in nonstandard analysis but considered rigorous until the 20th century; a fluxion in Newtonian calculus, now usually written in Leibniz's notation as operatorname d!x.

6. vi phân

   A function giving the change in the linear approximation of f at a point x over a small interval Δx or operatorname d!x, the function being called the differential of f and denoted operatorname d!f(x,Δx), operatorname d!f(x), or simply operatorname d!f.

   If f(x)#61;x², the differential of f is the function #92;operatorname#123;d#125;#92;#33;f(x,#92;Deltax)#61;f'(x)#92;Deltax#61;2x#92;Deltax.
