Question

find the value of tan{(19π)/3}

Answer 1

Hey !!!

tan( 19π/3 ) = tan ( 6π + π/3 ) ➡We can write ?

°•° it is in the form of (2πn + ¢ )

since , the angle must be in must 1st quadrant

and carectria of 1st quadrant is all identity positive ✔ and still all identity same

hence , tan( 6π + π/3 ) = tan (π/3 )

or, tan(180° /3 )

or, tan60° = √3 Answer ✔
