Question

what is the value of tan(1125)=?

Answer 1

Hi there! 

So, it's a fairly non-complicated problem. 

$tan(1125) = tan(\frac{1125}{360}) = tan(3\frac{45}{360})$

Knowing that, we can ignore three, full, $360'$ circles, what interests us is the remaining angle, which is $45'$

We know, from the trigonometric chart, that: 

$tan(45')=1$

Therefore, the answer is: 

$tan(1125)=1$


All the best!
