And now it is easy.

given: secQ = 5, then cosQ = 1/5

So we have a right angles triangle, where the hypotenuse is 5, the side adjacent to angle Q is 1, and the opposite to angle Q is 2√6

Notice that the second function, tanQ = 2√6 was not necessary, since we can see that from our triangle.

a) cosQ = 1/5

b) cotQ = 1/tanQ = 1/(2√6)

c) cot(90 - Q) = tan Q = 2√6

d) sinQ = 2√6/5
