Question

$\tan \left({44}^{\circ }\right)=?$

Given $\tan 1^0=0.0175$

Answer 1

Given that,

$\tan 1^0=0.0175$

Then value of

$\tan {44}^0=\tan ({45}^0-1^0)=\frac{\tan {45}^0-\tan 1^0}{1+\tan {45}^0\tan 1^0}$

$=\frac{1-0.0175}{1+1\times 0.0175}$

$=\frac{0.9825}{1.0175}$

$=\frac{9825}{10175}=0.9657$

Hence, this is the answer.
