Which function is equivalent to y= -cot(x)

Step-by-step explanation:

Given is a trignometric function in cotangent.

We have by trignometric rules cotx is reciprocal of tanx

Hence this is equivalent to

  ... i

Another way of writing is we have

tanx = cot (90-x) and cot x = tan (90-x)

Hence this can also be written as

In particular we do not want negative sign in the term means we can use the fact that cot x is negative in II quadrant

Hence the same function can be written as
