Luas daerah yang dibatasi kurva y = x² - 6x + 5 dan sumbu x pada batas x = 1 dan x = 4

[+50]

Luas daerah yang dibatasi kurva y = x² - 6x + 5 dan sumbu x pada batas x = 1 dan x = 4

Penjelasan dengan langkah-langkah:

y = x² - 6x + 5

'y = ⅓x³ – 3x² + 5x

4

integral (x² – 6x + 5x) dx

1

4

Luas = – [ ⅓x³ – 3x² + 5x]

1

= – ([⅓(4³) – 3(4²) + 5(4)] – [ ⅓(1³) – 3(1²) + 5(1)])

= – ([64/3 – 48 + 20] – [ ⅓ – 3 + 5])

= – ([64/3 – 84/3] – [7/3])

= –(–20/3 – 7/3)

= –(–27/3)

= 9 satuan luas
