To compute the integral of the expression ∫sin(x)xdx, follow these steps:1. Recognize that the integral ∫sin(x)xdx does not have a closed-form solution in terms of elementary functions.2. This integral is known as the Sine Integral, denoted as Si(x).3. The Sine Integral is defined...
integral belongs to a class of functions F(x)+C, where C is an arbitrary constant. Integral Calculator parses the expressions, applies integration rules and simplifies the final result. Therefore the final result of the integral computation might be different from what you expect by a constant....
The inverses of trigonometric functions are integrable as well. Sometimes, trigonometric formulas are required for their simplification. Answer and Explanation: First, we shall simplify the integrand and then evaluate it. {eq}\begin{aligned} \int{\sin }\frac{2x}{3}\sin......
