Example Question #41 : Definite Integrals
Evaluate this integral.
Answer not listed
In order to evaluate this integral, first find the antiderivative of
In this case, .
The antiderivative is .
Using the Fundamental Theorem of Calculus, evaluate the integral using the antiderivative:
Example Question #42 : Definite Integrals
Evaluate the following definite integral:
By a straightforward application of antiderivative rules for polynomial functions,
Example Question #43 : Definite Integrals
Evaluate the integral .
This integral is tricky, because there doesn't seem to be an apparent substitution method to use. The derivative of , , and seem to only complicate the integral further. However, we do note that the integral of is given by . Thus, we can use integration by parts here. Splitting into and letting and , this gives us and . Plugging this into the integration by parts formula, we get:
Unfortunately, this still looks more complicated than the original. However, using the trig identity on the second integral will give us something we can work with. Doing so we obtain:
Now here, we know how to evaluate the integral of , and we also have a copy of our integral subtracted on the right side. Therefore, we can add this integral to each side of the equation, eliminating it on the right side and leaving something we can evaluate. Doing so, we obtain:
Finally, dividing the whole equation by and replacing the constant with a new constant gives us our final result:

Using the Fundamental Theorem of Calculus, evaluate the integral using the antiderivative:
Example Question #44 : Definite Integrals
The antiderivative of is . Now, all we need to do is plug in our bounds, remembering it is always top - bottom bound.
In the last step, I simply rewrote into the denominator, getting rid of the negative exponent.
