Question

value of tan(-690°) is?​

Answer 1

$\huge{\underline{\sf{\red{Answer}}}}$

Tan(-690°)

Here the Angle given is Negative

i.e Clockwise direction in the graph

Here when we complete one round Clockwise

$\implies$ -690 + 360

$\implies$ -330°

______________________________________________

$\implies$ -330° in Clockwise direction is 30° in anticlockwise direction from 0°

I.e We have to find the value of Tan(30)°

Tan30° = $\large{\boxed{\frac{1}{\sqrt{3}}}}$
