Can you help me by giving me a method or solution
integrating sinx/x between (0,infinty)
please help me
integrating sinx/x between (0,infinty)
please help me
That's an approximation to [itex]\pi / 2[/itex]. Actually, the resultpixel01 said:sinx/x does not have the elementary primitive function. You can calculate it numerically by a program. I used Matlab and calculated it as :1.571
There wouldn't be much point in asking the question for a maths homework/question sheet if the answer was "Done by computer". For integrals such as sinx/x, particularly when the limits involve infinity, complex analysis is often the way to go.pixel01 said:sinx/x does not have the elementary primitive function.

For the benefit of the original poster mostly :robert Ihnot said:However, I took that course long ago and don't know all the steps.
An integral is a mathematical concept that represents the area under a curve in a graph. It is a fundamental concept in calculus and is used to find the total accumulated value of a function over a given interval.
Integrals are used in many fields of science, including physics, engineering, and economics, to name a few. They allow us to find important quantities such as displacement, velocity, acceleration, and work, among others. They also help us solve complex problems and make predictions about real-world phenomena.
There are several techniques for solving integrals, depending on the type of function and the desired outcome. The most common methods include using basic integration rules, substitution, integration by parts, and partial fractions. It is important to have a good understanding of calculus and practice solving different types of integrals to become proficient in solving them.
One example of an integral is finding the area under a curve. For instance, if we have a function f(x) = x^2 and we want to find the area under the curve between x = 0 and x = 2, we can use integration to solve it. The resulting integral would be ∫f(x) = x^2 dx = 8/3.
Integrals are essential in science because they allow us to analyze and understand various natural phenomena. Many physical laws and principles, such as Newton's laws of motion, can be expressed and understood through integrals. They also help us make accurate predictions and solve complex problems in fields such as physics, chemistry, and biology.
