1. Draw the graph of f(x) = cos x for 0 I know how to construct the graph but I don’t know how to get the figures. Please help
KengaRu [80]

Answer:

Please refer to the attached figure.

Step-by-step explanation:

Given the function:

f(x) =cosx \ where\  \{0^\circ\leq x\leq 360^\circ\}

OR, the given function can also be written as:

y  = f(x) = cosx

We know that graph of cosine is a wave.

and the range of cosine function is [-1, 1]

First of all, let us have a table of values at major values of x.

x = 0, f(x) = 1\\x = 90, f(x) = 0\\x = 180, f(x) = -1\\x = 270, f(x) = 0\\x = 360, f(x) = 1

So, the table of values for f(x) is:

\begin{center}\begin{tabular}{ c c }x & cosx \\0 & 1 \\90 & 0\\180 & -1\\270 & 0\\360 & 1\\\end{tabular}\end{center}

Let us mark these points on the xy coordinate axis where x axis represents value of<em> x </em>and y axis represents value of f(x)  = cosx and then join the points using a wave.

Please refer to the attached graph for the answer image.

Order the expressions from least value to greatest value.<br> I added a screenshot
Ivanshal [37]
-4.8x3.2 , 4.32/-3 , -2 3/5 - (1 2/5), 2 1/4+(-1 2/5)

So basically if they’re numbered from left to right then it would be 1, 3, 4, 2.

Problem 1 has a solution of -15.36
Problem 2 has a solution of 0.85
Problem 3 has a solution of -1.44
Problem 4 has a solution of -1.2

In order -15.36 would be the least greatest, because it is the farthest from zero. Followed by -1.44, -1.2, and lastly 0.85.
