1. The order of a differential equation is the order of the highest derivative in the equation.


2. a∫b f(x) dx = a∫b f(x) dx


3. Area bounded by the curve x = f(y) and x-axis is a∫b f(x)dx a £ x £ b.


4. d/dx {∫f(x)dx} = f(x) + c


5. The general solution of differential equation in variable separable form contains two independent variables


6. y = ce-x is solution of differential equation dy/dx = -y.


7. ∫ d/dx {f(x) } dx = f(x) + c.


8. dy = δy


9. ∫(ax+b) dx = (ax + b)n+1 /n+ 1 where n ε Z


10. a∫bf(x) dx has a definite value
