Question

xsquare +sin .find integration physics​

Answer 1

Answer:

$\rm \dfrac{x^3}{3} - cos \ x + C$

Explanation:

$\rm \int [x^2 + sin x]$

$\rm = \int x^2 \ dx + \int sin x \ dx$

(Sum rule)

$\rm = \dfrac{x^3}{3} - cos \ x + C$

(Power rule.)

As,

• $\rm \int x^n = \dfrac{x^{n+1}}{n+1} + C$
• $\rm \int sin \ (x) = - cos \ (x) + C$
