Given the following function, choose the graph with the two possible angles with the domain 0 < or = to theta < or = to 360 degrees. Sec(theta)= -13/5

I have reviewed the lesson that explains this three times, but I have ALWAYS had a hard time with Math and this is Pre-Cal. And I get so frustrated that I start to cry!!!! URRRGGGGHHHH!!!!

sec x is negative in QII,QIII

So, your angles will be between 90 and 270 degrees.

I do wish I had a tutor but right now my family doesn't have an income and I can't pay for a tutor. Since I live in Costa Rica everything here is expensive.

Have you considered a tutor? A few sessions with some good person-to-person coaching may be all you need. Invest a few bucks and it may be worth it. Too bad you don't live in Austin, TX, or I'd volunteer to do the job, as I do math tutoring all the time.

Bruh angles are greater than 360 degrees. Have a nice day

Sec(theta) = -13/5? Wow, sounds like that function could use a good therapist! Let's find the two possible angles that can make that happen.

Since sec(theta) is the reciprocal of cos(theta), we can find the value of cos(theta) by taking the reciprocal of -13/5, which would be -5/13.

Now, let's think about the values of cos(theta) on the unit circle. Cosine represents the x-coordinate of a point on the unit circle. Since we're dealing with negative values, we need to look for points that lie in the third and fourth quadrants.

In the third quadrant, cos(theta) is negative, and the corresponding angle is between 180 and 270 degrees. In the fourth quadrant, cos(theta) is also negative, and the corresponding angle is between 270 and 360 degrees.

So, the two possible angles that satisfy the equation sec(theta) = -13/5 with the given domain are in between 180 and 360 degrees.

As for the graph, imagine a unit circle without my clown shoes, and focus on the bottom-right area (third and fourth quadrants). There you go, that's where the magic is happening!

To determine the two possible angles in the given function Sec(theta) = -13/5, we need to find the values of theta where the secant function is equal to -13/5.

Secant is the reciprocal of the cosine function, so we can rewrite the equation as follows:

cos(theta) = -5/13

The cosine function represents the x-coordinate in the unit circle. Since the range of the cosine function is -1 to 1, we need to find when the x-coordinate is equal to -5/13.

To find these values, we can use the inverse cosine function (also known as arccosine or acos). The inverse cosine function allows us to find the angles at which the cosine value is equal to a given value.

Thus, we can calculate the two possible angles by using the inverse cosine function:

theta = arccos(-5/13)

Using a calculator or a math software, we find the approximate values of theta:

theta ≈ 138.59 degrees and theta ≈ 221.41 degrees

Now, we have the two possible angles, which are approximately 138.59 degrees and 221.41 degrees.

To choose the correct graph, we need to consider the domain of theta given in the question (0 ≤ theta ≤ 360 degrees). Since both of the angles are within this domain, the graph that correctly represents the given equation Sec(theta) = -13/5 would show these two angles.
