Gak nemu* jugaaa yg ini . tolong yaaaa .

Answer 1

Verified answer

Y = 4 sin x cos x + 1
y = 2 . 2 sin x cos x + 1
y = 2 sin 2x + 1

Maksimum --> y' = 0

y' = 0
2 . 2 cos 2x = 0
4 cos 2x = 0
2x = 0
x = 90°
x = 45°

Saat x = 45°

y = 2 sin (2 × 45°) + 1
y = 2 sin 90° + 1
y = 2 . 1 + 1
y = 3

Nilai maksimum = 3
