Question
Use the method of Example 4a to evaluate the definite integrals in Exercises 63-70$$\int_{-1}^{1} x^{3} d x$$
Step 1
The power rule states that the integral of x^n dx is equal to (x^(n+1))/(n+1) + C, where C is the constant of integration. In this case, n is 3. So, we have: $$\int_{-1}^{1} x^{3} d x = \frac{x^{3+1}}{3+1} = \frac{x^{4}}{4}$$ Show more…
