√2.sin(2x-15°) = 1
sin(2x-15°) = 1/√2
sin(2x-15°) = 1/2 √2
Dengan:
sin(2x-15°) = 45°
Diberikan solusi 1:
2x - 15° = 45° + k.360°
2x = 60° + k.360°
x = 30° + k.180°
Dengan k = 0 dan 1
Didapat:
x = {30°,210°}
Dan solusi 2:
2x - 15° = (180-45)° + k.360°
2x - 15° = 135° + k.360°
2x = 150° + k.360°
x = 75° + k.180°
Dengan k = 0 dan 1
Didapat:
x = {75°,255°}
Didapat:
HP = {x | 30°,75°,210°,255°}
