Question

Which of the following is a simpler way to write cos/sin

tan
sec
csc
cot

Answer 1

One simple trigonometric identity is:

`Tan x = (Sin x)/( Cos x)`

Also, from basic trigonometric ratios, we know that:

`Tan x = (1)/(Cot x)`

Substituting, we can solve and see what Cos/Sin is:

`(1)/(Cot x) = (Sin x)/(Cos x)`

We can take the reciprocal of both sides:

`Cot x = (Cos x)/(Sin x)`

So, the ratio of COT is COS/SIN.

ANSWER: cot
