Find the integral of the given function: 1/cos(x - a) cos(x - b) Evaluate the definite integral \displaystyle{ I = \int\limits_0^{\pi/4} \dfrac{ 4 \cos(x) 3 \sin(x) }{\cos^3(x)}dx. } Evaluate the indefinite integral: integral {7 - 4 sin(x)} ...
For instance, it is known that {eq}\frac{d}{dx} \sin(x) = \cos(x) {/eq} and, therefore, one antiderivative of cos(x) is sin(x). A note to say that typically the general antiderivative involves a + c term at the end since the derivative of a constant is zero. The ...
