Help with this algebra math question please

Answer 1

For this case, the first thing you should know is that the cotangent is the inverse function of the tangent.
 We have then:
 cot (x) = 1 / (tan (x))
 Rewriting we have:
 cot (x) = 1 / ((sin (x)) / (cos (x)))
 We do double c:
 cot (x) = cos (x) / sin (x)
 Answer:
 cot (x) = cos (x) / sin (x)
