Chapter 2, Problem 1P

To determine

To create:

A row vector with the following elements: $8,\frac{10}{4},12\times 1.4,51,\tan 85°,\sqrt{26}$ and $0.15$.

Answer to Problem 1P

Solution:

The created row vector is:

$\text{Row}=[\text{8}\text{.0000}\text{ 2}\text{.5000}\text{ 16}\text{.8000}\text{ 51}\text{.0000}\text{ 11}\text{.4301}\text{ 5}\text{.0990}\text{ 0}\text{.1500}]$

Explanation of Solution

The given row vector contains following elements: $9,1,3^2,7/4,0,2.25\times 8.5,0.8$ and $\sin \left(\text{π}/\text{8}\right)$.

Simplify the given row vectoras:

$\begin{array}{c}8=8\\ \frac{10}{4}=2.5\\ 12\times 1.4=16.8\\ 51=51\end{array}$

$\begin{array}{c}\tan 85°=11.4301\\ \sqrt{26}=5.0990\\ 0.15=0.15\end{array}$

Hence, the created row vector is:

$\text{Row}=[\text{8}\text{.0000}\text{ 2}\text{.5000}\text{ 16}\text{.8000}\text{ 51}\text{.0000}\text{ 11}\text{.4301}\text{ 5}\text{.0990}\text{ 0}\text{.1500}]$

Write the MATLAB script that creates a row vector with the following elements: $8,\frac{10}{4},12\times 1.4,51,\tan 85°,\sqrt{26}$ and $0.15$.

MATLAB Code:

%MATLAB code to create a row vector a.

a_row = [8 10/4 12*1.4 51 tand(85) sqrt(26) 0.15]

Save the MATLAB script with the name, chapter2_29864_2_1P.m in the current folder. Execute the script by typing the script name at the command window to get the answer for a row vector with the following elements: $8,\frac{10}{4},12\times 1.4,51,\tan 85°,\sqrt{26}$ and $0.15$.

Result:

Conclusion:

Therefore, the created row vector is:

$\text{Row}=[\text{8}\text{.0000}\text{ 2}\text{.5000}\text{ 16}\text{.8000}\text{ 51}\text{.0000}\text{ 11}\text{.4301}\text{ 5}\text{.0990}\text{ 0}\text{.1500}]$.
