# Definite Integrals

Share0 Share +10 Tweet0 Background of Definite Integrals Definite Integrals are calculated by subtracting the function values of upper and lower limits. $$\displaystyle \int_{a}^{b}{f(x)}dx = F(a) – F(b), \text{where } \frac{d}{dx}F(x) = f(x)$$ Practice Questions Question 1 Evaluate $\displaystyle \int_{0}^{2}{6x}dx$. Question 2 Evaluate $\displaystyle \int_{2}^{4}5dx$. Question 3 Evaluate $\displaystyle \int_{1}^{3}{(2x+4)}dx$. Question […]
