To solve this, just multiply and then make the answer negative:

Use the same strategy you used above to solve this equation:

Explanation:
HI, so it’s very simple if you read this it will be really easy for you in the future! So basically, looking at it, it’s basically multiplying but what confuses you are the signs (-)(negative) and (+)(positive). All you have to know is:
Positive number x positive number = positive answer
Negative number x negative number= positive answer
Positive number x negative number= negative answer
Negative number x positive number= negative answer
And as long as you know this it will be really easy for you. So just multiply as usual normally and then according to the rules find out if the answer will be negative or positive.
Look at the following picture to understand the rules more clearly>>

<h2>Hello!</h2>
The answer is:
Domain and range of trigonometric functions are already calculated, so let's discard one by one in order to find the correct answer.
The range is where the function can exist in the vertical axis when we assign values to the variable.
First:
: Incorrect, it does include 0.4 since the cosine range goes from -1 to 1 (-1 ≤ y ≤ 1)
Second:
: Incorrect, it also does include 0.4 since the cotangent range goes from is all the real numbers.
Third:
: Correct, the cosecant function is all the real numbers without the numbers included between -1 and 1 (y≤-1 or y≥1).
Fourth:
: Incorrect, the sine function range is equal to the cosine function range (-1 ≤ y ≤ 1).
I attached a pic of the csc function graphic where you can verify the answer!
Have a nice day!
