Evaluate the expressions: arctan(-√3) arctan(-√3)

Solution:-

To evaluate

Consider a right angle triangle with base angle x =

⇒tan x =

We know that for=60°,  tan(60°)=

here the value is so it will lie in 2nd or 4th quadrant.

For 2nd quadrant the value of x will be x=180°-

⇒ x=180°-60°=120°.

For 4th quadrant the value of x will be x=360°-

⇒ x=360°-60°=300°.

In radian

For 2nd quadrant the value of x will be x=180°-

⇒ =1.04(approx)

For 4th quadrant the value of x will be x=360°-

⇒ .

it would open into a square depending on the type of envelope i’m not sure about the second part
