Value of tan(90 - cot^-1(1/3))

0.36

Step-by-step explanation:

We need to solve the first bracket first and then the others,

    Value of  Cos^ - 1(1/3) =70.53°

        Then,  90 - the value of cosine

             =19.47°

Then, put the new in the calculator:

     Tan (19.47°)

and the answer comes 0.3535294237

 then I use the nearest formula and got the answer = 0.36
