What is [itex]\int y dy[/itex]? What do you get when you put y= sin(x) into that? Now, what is the integral of that with respect to x? (You may need a trig identity.)chevy900ss said:Integrate

The given expression is a double integral, which represents the area under the curve of the function y=sinx, bounded by the lines x=0, x=pi, y=0, and y=sinx.
To solve this integral, you can first integrate with respect to y, treating x as a constant, which will give you the integral of sinx. Then, integrate the result with respect to x, treating y as a constant, which will give you the final answer.
The first step is to integrate with respect to y, treating x as a constant. This will give you the integral of sinx with respect to y, which is -cosx. Then, integrate the result with respect to x, treating y as a constant. This will give you the final answer of -2cosx, evaluated from x=0 to x=pi.
Integrating double integrals is important in many fields of science, including physics, engineering, and economics. It allows us to calculate the volume under a curved surface, which has various applications in these fields.
Yes, there are various methods for solving double integrals, including using polar coordinates, changing the order of integration, and using numerical methods. However, the method used to solve this integral may vary depending on the specific function and limits given.
