Tanx=-4

use ur calculator and find the inverse tangent of -4

the answer u get is theta then u multiply the answer by
pi_
180

3. i got -1.32 as theta then mulyiplies by pi/180 and got -75.63 and it says im wrong

change the mode to degrees

$\displaystyle \theta=arctan( -4)$

$\displaystyle \theta\approx-1.325817664$ radians.

Reference angle in QII = $\displaystyle -1.325817664 + \pi=1.81577499$ radians.To the nearest 2 decimal places ==> 1.82 radians.

sry forgot it was in QII
