True or False? The graph of sine can be used to construct the graph of the secant function.

amid [387]

True

Note that:

$secant \theta = \frac{1}{cos\theta}$

The graph of sine and cosine functions are very similar. They only have a shift in the x -axis.

That is, sin x = cos (90 - x)

Since there is a great similarity between the sine and cosine graphs, and the secant graph is an inverse of the cosine graph, the graph of sine can be used to construct the graph of the secant function

Mathematically:

since sec x = 1 / cos x

and, cos x = sin (90 - x)

therefore, sec x = 1 / sin (90 - x)

The graphs of the sine and secant functions are attached to this solution

A student was asked to find the slope of the line through the points (4,8) and (-3,5). His answer, <img src="https://tex.z-dn.ne

evablogger [386]

Answer:

$m=\frac{-3}{-7}$

Step-by-step explanation:

Given the following question:

Point A = (4, 8) = (x1, y1)
Point B = (-3, 5) = (x2, y2)

In order to find the slope any two points given we use the formula to find slope or rise/run.

$m=\frac{y2-y1}{x2-x1}$
$m=\frac{5-8}{-3-4} =\frac{-3}{-7}$
$m=\frac{-3}{-7}$

The reason why the students answer is incorrect because he substituted incorrectly. More specifically the run part of the formula for slope. The formula for slope goes x2 - x1 which means it should be -3 - 4, not -4 - 3, which will give you the answer -7.

Hope this helps.
