The relationship between the limit of a function and a definite integral on a given integral is given by:
![\int\limits^b_a {f(x)} \, dx = \lim_{n \to \infty} \Sigma_{n=1}^nf(x_i)\delta x,\ \ [a,\ b]](https://tex.z-dn.net/?f=%20%5Cint%5Climits%5Eb_a%20%7Bf%28x%29%7D%20%5C%2C%20dx%20%3D%20%5Clim_%7Bn%20%5Cto%20%5Cinfty%7D%20%5CSigma_%7Bn%3D1%7D%5Enf%28x_i%29%5Cdelta%20x%2C%5C%20%5C%20%5Ba%2C%5C%20b%5D)
Given![\lim_{n \to \infty} \frac{\cos x_i}{x_i} \delta x,\ \ [2\pi,\ 3\pi]](https://tex.z-dn.net/?f=%20%5Clim_%7Bn%20%5Cto%20%5Cinfty%7D%20%20%5Cfrac%7B%5Ccos%20x_i%7D%7Bx_i%7D%20%20%5Cdelta%20x%2C%5C%20%5C%20%5B2%5Cpi%2C%5C%203%5Cpi%5D)
, the equivalent definite integral is:
Given
Step-by-step explanation:
First, let x represent this unknown number because we are using an equation to solve this. Note that 'of' means multiplication.
First we cross out to get;
30 =
Then we multiply both sides of the equation by 3
90 = 2x
Now since we want x to stand alone, we divide both sides by 2
45 = x
So the answer is 45
<u>Second Problem</u>
First we find how far Ken jumps.
1 ÷ 5 = 0.2. If this is attached to the one it means Ken jumped 1.2 metres.
To find how much further Steve jumped, we just have to subtract Ken's distance from Steve's distance.
1.5 - 1.2 = 0.3 metres
This means Steve jumped 0.3 metres further than Ken.
