To find tanyou first find tan, then you square that.  smiley

 

tan2 30° = (tan 30°)x(tan 30°)

Tangent is a function, and tan2 have no value.

Of course Max is correct, there has to be an angle there. :)

or

(tan30)^2 = 1/3

 

The calc changes it to tan30^2 but that is ok :)

 

(tan(30))^2 = 0.3333333333337655

 

It should just be 1/3 so there is some rounding error.
