The integral as a limit of Riemann sums using right endpoints is =lim (n→∞) n ∑i=1[(ln(1+(4+8i/n)2)−sin(4+8i/n))8/n].

The definite integral is defined here in terms of its limit.

So the definite integral goes as follows.

∫f(x)dx= lim(n→∞) n∑i=1 f(xi)Δx.

Where, for each positive integer n, we let Δx=(b−a) /n

And in case of i=1,2, 3..., n, we let xi=a+iΔx.

For Δx

For each n, we get

Δx=(b−a)/n= (12−4)/n=8/n

For xi

Xi = a+iΔx = 4+i8/n=4+8i/n

For f(xi)

∫124 [ln(1+x2) −sin x] dx

=lim (n→∞) n ∑i=1[(ln(1+(4+8i/n)2)−sin(4+8i/n))8/n]

The Riemann integral, developed by Bernhard Riemann, was the first exact formulation of the integral of a function over an interval in the field of mathematics known as real analysis.

It was presented to the faculty at the University of Göttingen in 1854, but it wasn’t until 1868 that it was published in a journal.

The Riemann integral can be found using the calculus fundamental theorem for a variety of functions and real-world situations, or it can be roughly approximated using numerical integration.

The Riemann integral can be thought of as the limit of a function’s Riemann sums as the finer the partitions are.

The function is referred to as being integrable if the limit exists (or more specifically Riemann-integrable). By making the partition fine enough, the Riemann sum can be brought as close as desired to the Riemann integral.

The mesh of the partitions must, among other things, get smaller and smaller until, at the limit, it is zero.

If this were not the case, then on specific subintervals, we would not be receiving a fair approximation to the function. Actually, this is sufficient to define an integral.

The amount of heat that one gram of a material needs either absorb or lose in order to alter its temperature by a degree Celsius is known as specific heat. This equates to one caloric, or 4.184 Joules, for water.

Although the hydrogen bonds in water are much too weak to be compared to intra - molecular bonds like covalently or ionic bonds, they are nevertheless strong enough to require a lot of energy to break. Water boils at 100°C for this reason.

The difference quotient that best approximates the instantaneous rate of change is 1.

Average rate of change is rate at which one value within a function changes in relationship to another. The average rate of change is usually used to determine slope of a graphed function.

Let's explore how to find average rate of change and use linear and nonlinear functions to demonstrate it.

The average rate of change the formula is used to find the slope of a graphed function. To find average rate of change, divide the change in y-values by the change in x-values.

Finding average rate of change is particularly useful for determining changes in measurable values like average speed or average velocity.

We can define average rate of change of a function f(x) in interval [a, b] as:

[tex]r=\frac{f_{b}-f_{a} }{b-a}[/tex]

Particularly, if we want to find an approximation of rate of change for a particular value x', we can choose:

a < x' < b

Such that a and b are close to x'.

Then if we want to find the instantaneous rate of change of g at x = 0, we need to find the values of a and b really close to zero.

Looking at the table, we can choose:

a = -0.001

b = 0.001

(are two closer ones to zero)

Then rate of the change can be written as:

[tex]f(x)=\frac{g(0.001)-g(-0.001)}{0.001-(-0.001)}=\frac{2.001-1.999}{0.002}=1[/tex]

The motion of the rocket labeled a is an example of motion with uniform (i.e., constant) velocity and non- zero acceleration.

A body when covers an equal distance with an equal interval of time, this condition of the velocity is known as uniform velocity. Or, we can say that when the direction and magnitude of speed of a body do not change with time, then the body is said to be at uniform velocity.

Having a non-zero acceleration means having any amount of acceleration whatsoever. This could be either positive acceleration or negative acceleration (a.k.a. deceleration).

An object experiences a non-zero acceleration when it is speeding up, slowing down, or remaining at the same speed while changing direction. Any of these three scenarios would result in an object's velocity changing since velocity is the change in an object's position over time, and a change in velocity means the object is experiencing acceleration.

Conversely, an object has zero acceleration when it either remains stationary or moving at a constant speed in a straight line. In both of these scenarios, the velocity of the object is constant, so there is no acceleration.
