Lab Report Questions:

Plot Sin and Cos function plots from $0$ radian to $2$ radians with $x$ axis labeled 'Radians' and $Y$ axis labeled 'Sine and Cosine Functions' with:

a$."$pi$0\mathrm{.}01"$ linear spacing

$($Hint: Use $x=0$:$**0\mathrm{.}2$:$2**)$

$($Hint: Use $x=0$:$**0\mathrm{.}01$:$2**)$

DO NOT TAKE A SCREEN SHOT! USE 'SAVE FIGURES AS IMAGES' OPTION AS DEFINED ABOVE.

What are the minimum and maximum values of each trigonometric function?

Does the increment $($linear spacing value$)$ change the min and max values? Explain why?

What does linear spacing value change?

Write at least one error message you have seen during this lab.

Array Generation and Indexing:

array$1=\left[\begin{array}{ccccc}0\mathrm{.}0& 0\mathrm{.}5& 2\mathrm{.}1& -3\mathrm{.}5& 6\mathrm{.}0\\ 0\mathrm{.}0& -1\mathrm{.}1& -6\mathrm{.}6& 2\mathrm{.}8& 3\mathrm{.}4\\ 2\mathrm{.}1& 0\mathrm{.}1& 0\mathrm{.}3& -0\mathrm{.}4& 1\mathrm{.}3\\ 1\mathrm{.}1& 5\mathrm{.}1& 0\mathrm{.}0& 1\mathrm{.}1& -2\mathrm{.}0\end{array}\right]$

$[$Execute these questions in the command window$]$

a$)$ Generate the array above. $($Hint: Use arrayl $=[0\mathrm{.}00\mathrm{.}52\mathrm{.}1-3\mathrm{.}56\mathrm{.}0$;$0\mathrm{.}0$dotsdots???$]$

b$)$ What is the size of array$1?($Hint: Use size function in command window.$)$

c$)$ What is the value of array $1(1,4)?$

d$)$ Evaluate the output of max $($array$1).$ Describe its function. $($Hint: doc max and figure out how to use it and explain in one sentence.$)$

e$)$ BONUS $[$DO IT YOURSELF$]-$ Search online and find the solution yourself: How can we find the maximum of the complete array?

Array size: Determine the size and contents of the following arrays $($Take a screenshot of each output$).$ Note that the later arrays may depend on the definitions of arrays defined earlier in this exercise. Understand each output well, you will need it in the next lab and following topics.

$[$Execute these questions in the command window$]$

a$)a=2$:$3$:$8$; Initializing a variable with linear spacing of $3$

b$)b=[a^{\text{'}}{a}^{\text{'}}{a}^{\text{'}}]$; $\%$ranspose Example

c$)c=$zeros$(1,3)$; $$ Automatic initialization

d$)$ Analyze the output of previous question$($c$).$ What does zeros function generate? Check 'doc zeros' to gain more information.
