OpenStudy (mathaphobia):

cot(x) = 1/tan(x) right?

Mehek (mehek14):

correct

OpenStudy (mathaphobia):

Okay so my answer is correct then right?

Mehek (mehek14):

tan = \(\dfrac{opposite}{adjacent}\)

OpenStudy (mathaphobia):

Right I knew that which is why it makes sense.

Mehek (mehek14):

cot would be the opposite \(\dfrac{adjacent}{opposite}\)

OpenStudy (mathaphobia):

Right because 1/tan(x) everything flips.

Mehek (mehek14):

So B would be incorrect

OpenStudy (mathaphobia):

Ah okay so let me look at this again.

OpenStudy (mathaphobia):

sec(x) = 1/cos(x) right?

OpenStudy (mathaphobia):

cosec(x) = 1/sin(x)?

Mehek (mehek14):

Yes

OpenStudy (mathaphobia):

Okay so it would be D then right?

Mehek (mehek14):

Yep

OpenStudy (mathaphobia):

Awesome thank you!

Mehek (mehek14):

You're welcome :)
