Solve the given equation over the interval [0, 2π): csc^2 x + 2 csc x = 0.

Anastaziya [24]

$csc^2x+2cscx=0$
Factor out the GCF which is csc x
$cscx(cscx+2)=0$
Set each factor equal to zero.
$cscx=0$ or $cscx+2=0$
Using the reciprocal sine function we can replace csc in the equations.
$\frac{1}{sinx} =0$ or $\frac{1}{sinx} +2=0$
The first equation yields 1 = 0 which is not true. However the second equation does offer 2 possible answers.
When solved for sinx you get $sinx=- \frac{1}{2}$
The sine function is negative in the 3rd and 4th quadrants.
You can use the unit circle or the $sin^-^1$ feature on your calculator $sin^-^1(1/2)$
$210^o or 330^o$ alter radian answer which is probably what you want is $\frac{7 \pi }{6} or \frac{11 \pi }{6}$

Moby practiced solving addition and subtracting problems, but he made a mistakes! Explain any error you find, and include what’s

Maksim231197 [3]

Answer:

3/4 - 5/12 = 4/12 - 5/12 = -1/12

Step-by-step explanation:

Moby's addition and subtracting problem is as follows: Let us break the problem into solvable parts.

3/4 - 5/12

we will find the common factor of the denominator which are 4 and 12. The common factor is 12. We divide 12 by both denominator and multiply by the numerator .

3/4-5/12 = (9 - 5)/12 = 4/12 . This is his first error . 3/4 - 5/12 is equal to 4/12 not 3/12.

Now let us go to the second part which is the answer minus 5/12

4/12 - 5/12 = (4 - 5)/12 = -1/12

The final answer should be -1/12. This is another error that has been detected.

The correct answer combination should be as follows.

3/4 - 5/12 = 4/12 - 5/12 = -1/12
