Anonymous. $\begin{gathered} I = \int {\left( {\frac{{1 – \cos 2x}}{2}} \right)dx} \\ \Rightarrow I = \frac{1}{2}\int {\left( {1 – \cos 2x} \right)dx} \\ \Rightarrow I = \frac{1}{2}\int {1dx – \frac{1}{2}\int {\cos 2xdx} } \\ \end{gathered}$, Using the integral formula $$\int {\cos kxdx = \frac{{\sin kx}}{k} + c}$$, we have Graph the double hump of the sine^2 and you can easily see that 1/2 is not correct. set u = - x then we find du = - dx substitute du= - dx, u= - x = (1/2) e x + (1/2) - e-x dx = (1/2) e x + (1/2) e u du . $\begin{gathered} \int {{{\sin }^2}x} dx = \frac{1}{2}x – \frac{1}{2}\frac{{\sin 2x}}{2} + c \\ \Rightarrow \int {{{\sin }^2}x} dx = \frac{1}{2}x – \frac{1}{4}\sin 2x + c \\ \end{gathered}$. 1 decade ago. And it's strangely satisfying to … = (1/2) e x dx - (1/2) e-x dx solve left equation = (1/2) e x - (1/2) e-x dx . From the limit definition of the derivative, we know that d d x sin ⁡ x = cos ⁡ x \frac{d}{dx}\sin x=\cos x d x d sin x = cos x. The function can be found by finding the indefinite integral of the derivative. CEO Compensation and America's Growing Economic Divide. It is not a fundamental theorem telling you to find an antiderivative F whenever you seek an integral ∫ f d x. Since cos ⁡ x \cos x cos x is the derivative of sin ⁡ x \sin x sin x, from the definition of antiderivative the antiderivative of cos ⁡ x \cos x cos x must be sin ⁡ x \sin x sin … A COVID-19 Prophecy: Did Nostradamus Have a Prediction About This Apocalyptic Year? Worked problem in calculus. Let . Set up the integral to solve. Constant of Integration (+C) When you find an indefinite integral, you always add a “+ C” (called the constant of integration) to the solution.That’s because you can have many solutions, all of which are the set of all vertical transformations of the antiderivative.. For example, the antiderivative of 2x is x 2 + C, where C is a constant. Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share … Antiderivative for (x)(1-x)^2 = Antiderivative for (x^3 - 2x^2 + x)dx = .. 0 0.
