Pilih satu aja kah sin 5x = -1 sin 5x = sin 270 syarat 1 5x = 270 + k .360 x = 54 + k . 72 jika k = 0 maka x = 54 + 0 = 54 k = 1 maka x = 54 + 72 = 126 k = 2 maka x = 54 + 144 = 198 k = 3 maka x = 54 + 216 = 270 k = 4 maka x = 54 + 288 = 342 syarat 2 5x = (180 - 270) + k .360 5x = -90 + k.360 x = -18 + k 72 jika k = 1 maka x = -18 + 72 = 54 k = 2 maka x = -18 + 144 = 126 k = 3 maka x = -18 + 216 = 198 k = 4 maka x = -18 + 288 = 270 k = 5 maka x = -18 + 360 = 342 Jadi HP = { 54,126,198,270,342}
sin 5x = -1
sin 5x = sin 270
syarat 1
5x = 270 + k .360
x = 54 + k . 72
jika k = 0 maka x = 54 + 0 = 54
k = 1 maka x = 54 + 72 = 126
k = 2 maka x = 54 + 144 = 198
k = 3 maka x = 54 + 216 = 270
k = 4 maka x = 54 + 288 = 342
syarat 2
5x = (180 - 270) + k .360
5x = -90 + k.360
x = -18 + k 72
jika k = 1 maka x = -18 + 72 = 54
k = 2 maka x = -18 + 144 = 126
k = 3 maka x = -18 + 216 = 198
k = 4 maka x = -18 + 288 = 270
k = 5 maka x = -18 + 360 = 342
Jadi HP = { 54,126,198,270,342}
