Evaluate the line integral, where c is the given curve. C (x/y) ds, c: x = t3, y = t4, 1 ≤ t ≤ 4.

skelet666 [1.2K]

We have

x = t³ ===> dx/dt = 3t²

y = t⁴ ===> dy/dt = 4t³

Then with the given parameteriztion, the line integral along C of x/y is

$\displaystyle \int_C \frac xy \, ds = \int_1^4 \frac{t^3}{t^4} \sqrt{(3t^2)^2 + (4t^3)^2} \, dt$

$\displaystyle \int_C \frac xy \, ds = \int_1^4 \frac1t \sqrt{9t^4 + 16t^6} \, dt$

$\displaystyle \int_C \frac xy \, ds = \int_1^4 \frac{\sqrt{t^4}}t \sqrt{9 + 16t^2} \, dt$

$\displaystyle \int_C \frac xy \, ds = \int_1^4 \frac{t^2}t \sqrt{9 + 16t^2} \, dt$

$\displaystyle \int_C \frac xy \, ds = \int_1^4 t \sqrt{9 + 16t^2} \, dt$

$\displaystyle \int_C \frac xy \, ds = \frac1{32} \int_1^4 32t \sqrt{9 + 16t^2} \, dt$

$\displaystyle \int_C \frac xy \, ds = \frac1{32} \int_1^4 \sqrt{9 + 16t^2} \, d\left(9+16t^2\right)$

$\displaystyle \int_C \frac xy \, ds = \frac1{32} \cdot \frac23 \left(9+16t^2\right)^{\frac32}\bigg|_1^4$

$\displaystyle \int_C \frac xy \, ds = \frac1{48} \left(265^{\frac32} - 25^{\frac32}\right) = \boxed{\frac{265\sqrt{265}-125}{48}}$

Question 1 fill in the blank: every database has its own formatting, which can cause the data to seem inconsistent. Data analyst

harkovskaia [24]

Data analysts use the <u>CLEAR FORMAT</u><u> </u>tool to create a clean and consistent visual appearance for their spreadsheets.

<h3>Database </h3>

A database is an organized collection of data stored in a general or personal computer A database can be created with spreadsheets in order to produce a clean and consistent data for the purpose of study and analysis.

Every database has it own formatting and this leads to data inconsistency as well. To avoid inconsistency of data, Data is cleaned by analysts with the use of the tool clear format.

Hence we can conclude that Data analysts use the <u>clear format </u>tool to create a clean and consistent visual appearance for their spreadsheets.
