Name three values of x that would result in <br> y = cot x being undefined.

tester [92]

Three values of x that would result in y = cot x being undefined are $0,\pi ,2\pi$

Given :

y=cot(x)

we need to find where cot(x) is undefined

We know that $cot(x)=\frac{cotx}{sinx}$

when the denominator is 0 then we can say cot(x) is undefined

Lets find out x values that makes sin(x) as 0

We know that sin(0)=0

$sin(\pi )=0\\sin(2\pi )=0$

x values values that makes sin(x)=0 are $0,\pi ,2\pi$

These x values makes the denominator of cot(x) as 0 and it is undefined

So , three values of x that would result in y = cot x being undefined are $0,\pi ,2\pi$

Rearrange the equation so m is the independent variable. -2m-5n=7m-3n<br> Please answer FAST

IgorLugansk [536]

Answer:

$n=-4.5m$

Step-by-step explanation:

solve for n so that m becomes the independent variable

$-2m-5n=7m-3n$

$-5n=9m-3n$

$-2n=9m$

$n=-4.5m$
