Then , so . sin(x)dx = - cos(x) + c cos(x)dx = sin(x) + c sec 2 (x)dx = tan(x) + c These are the opposite of the trigonometric derivatives. Divide by . Worked problem in calculus. Since A COVID-19 Prophecy: Did Nostradamus Have a Prediction About This Apocalyptic Year? Since sinc is an even entire function (holomorphic over the entire complex plane), Si is entire, odd, and the integral in its definition can be taken along any path connecting the endpoints. So consider the second function as $$1$$. \[\begin{gathered} I = \int {\left( {\frac{{1 – \cos 2x}}{2}} \right)dx} \\ \Rightarrow I = \frac{1}{2}\int {\left( {1 – \cos 2x} \right)dx} \\ \Rightarrow I = \frac{1}{2}\int {1dx – \frac{1}{2}\int {\cos 2xdx} } \\ \end{gathered} \], Using the integral formula $$\int {\cos kxdx = \frac{{\sin kx}}{k} + c} $$, we have Simplify with factoring out.
