Integral Dalam Matematika 1

Integral merupakan kebalikan dari diferensial atau turunan. Jika y = f(x) + k ( konstanta ), maka turunan pertama y terhadap x adalah y' = f'(x).

Rumus Integral

Rumus integralnya ditulis sebagai berikut:

∫ f'(x) dx = f(x) + k

A. Integral Tak Tentu

Integral tak tentu adalah proses untuk menentukan bentuk umum anti turunan dari suatu fungsi yang diberikan, atau dikatakan hasil pengintegralan f(x) masih mengandung konstanta (k) sembarang.

∫ f'(x) dx = f(x) + k
