To find the definite integral of ( x^6 ) over the interval ([b, 2b]), you first need to find the antiderivative of ( x^6 ), which is ( \frac{1}{7}x^7 ). Then, you evaluate this antiderivative at the upper and lower bounds of the interval and subtract the lower bound value from the upper bound value. So the definite integral is:

[ \left[ \frac{1}{7}x^7 \right]_{b}^{2b} = \frac{1}{7}(2b)^7 - \frac{1}{7}b^7 ]

Simplifying this expression gives:

[ \frac{128}{7}b^7 - \frac{1}{7}b^7 = \frac{127}{7}b^7 ]

Therefore, the definite integral of ( x^6 ) over the interval ([b, 2b]) is ( \frac{127}{7}b^7 ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
