Question

Evaluate tan^-1(95) to 2 decimal places in degrees. If necessary, use 3.1416 as an approximation to pi.

Answer 1

$\begin{equation*} θ\approx1.56 \end{equation*}$

1) We can get started by evaluating the arctangent of angle 95º:

$\begin{gathered} \theta=\tan^{-1}(95) \\ θ=1.56027 \end{gathered}$

Note that since this is not a recurrent angle, there are no values in terms of pi. So we can tell the answer is:

$θ\approx1.56$

2)This is the answer to the nearest hundredth.
