Question

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

Answer 1

0.36

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
