<h3>
What is meant by definite integral?</h3>
A definite integral uses infinitesimal slivers or stripes of the region to calculate the area beneath a function. Integrals can be used to represent a region's (signed) area, the cumulative value of a function changing over time, or the amount of a substance given its density.
Definite integral, a term used in mathematics. is the region in the xy plane defined by the graph of f, the x-axis, and the lines x = a and x = b, where the area above the x-axis adds to the total and the area below the x-axis subtracts from the total.
If an antiderivative F exists for the interval [a, b], the definite integral of the function is the difference of the values at points a and b. The definite integral of any function can also be expressed as the limit of a sum.
Let the equation be
![$\int_a^b f(x) d x=\lim _{n \rightarrow \infty} \sum_{i=1}^n f\left(x_i\right) \Delta x$](https://tex.z-dn.net/?f=%24%5Cint_a%5Eb%20f%28x%29%20d%20x%3D%5Clim%20_%7Bn%20%5Crightarrow%20%5Cinfty%7D%20%5Csum_%7Bi%3D1%7D%5En%20f%5Cleft%28x_i%5Cright%29%20%5CDelta%20x%24)
substitute the values in the above equation, we get
=
on [2π, 4π],
simplifying the above equation
![$\int_{2\pi}^{4 \pi} \frac{\cos x}{x} d x$$](https://tex.z-dn.net/?f=%24%5Cint_%7B2%5Cpi%7D%5E%7B4%20%5Cpi%7D%20%5Cfrac%7B%5Ccos%20x%7D%7Bx%7D%20d%20x%24%24)

Answer:
The first one is 0, the second one is ARN (All real numbers)
Step-by-step explanation:
1. Anything raised to the "zeroth" power is always 1
2. Because 7 is being raised to the zeroth power, the number inside the parentheses becomes 1. Now x can equal anything, 1 times itself will always equal 1, no matter how many times you multiply them.
