Given the trigonometric value:

cot x =  1.5

Find tan x.

Solution:

In order to determine the value of tan x we simply apply the concept of trigonometric identities, specifically reciprocal identities.

sin = 1 / csc

cos = 1/ sec

tan = 1/cot

csc = 1/sin

sec = 1/cos

cot = 1/tan

Simply substitute the value of 1.5 to the formula for the tangent reciprocal.

tan x = 1/cot x

tan x = 1/1.5

tan x = 0.6666…

Since we have a repeating decimal, we can either equate it with a repeating word enclosed with a parenthesis, a dash line or an ellipsis. In our case we will use the ellipsis.

Final answer:

tan x = 0.6666…
