Evaluate tangent ^-1 1

Vitek1552 [10]

ANSWER

${ \tan }^{ - 1} (1) = 45 \degree$

${ \tan }^{ - 1} (1) = \frac{\pi}{4}$

EXPLANATION

We want to evaluate:

${ \tan }^{ - 1} (1)$

We can use scientific calculator to evaluate this directly to obtain:

${ \tan }^{ - 1} (1) =45\degree$

${ \tan }^{ - 1} (1) = \frac{\pi}{4}$

You could have also let:

$x = { \tan }^{ - 1} (1)$

Then,

$\tan(x) = 1$

The angle whose tangents is 1 is

$x =45\degree$

$x = \frac{\pi}{4}$

16 3/4 hours in two days plan to work 12 3/4 hour the next two days. How many hours will u total on your time sheet for these 4

sergiy2304 [10]

let's firstly convert the mixed fractions to improper fractions and then add up all four days.

$\bf \stackrel{mixed}{16\frac{3}{4}}\implies \cfrac{16\cdot 4+3}{4}\implies \stackrel{improper}{\cfrac{67}{4}}~\hfill \stackrel{mixed}{12\frac{3}{4}}\implies \cfrac{12\cdot 4+3}{4}\implies \cfrac{47}{4} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{all 4 days summed up}}{\cfrac{67}{4}+\cfrac{47}{4}}\implies \cfrac{67+47}{4}\implies \cfrac{114}{4}\implies \cfrac{57}{2}\implies 28\frac{1}{2}$
