Penyelesaian :Ingat bahwa :
tan a = sin a / cos a
Maka
tan^2 a · cos^2 a · 1/sin a = cos 60
( sin^2 a / cos^2 a ) · cos^2 a / sin a = 1/2
eliminasi cos^2 a
sin^2 a · 1/sin a = 1/2
sin a = 1/2
arc sin 1/2 = 30°
a = 30°
Maka
a = 30 +/- k · 360
a = (180 - 30) +/- k · 360
untuk k = 0
a = 150
Maka
hp = {30, 150} untuk interval 0 < a < 2pi
