1. ## integration 1

can yu help me solve it

2. ## Re: integration 1

If you meant $\int_{10}^{19}\frac{\sin(x)}{1+x^8}dx$:

$\int_{10}^{19}\frac{\sin(x)}{1+x^8}dx=-7.77628$ x $10^-9$

This is calculated by wolfram alpha.

I dont think that this integral can be evaluated by using elementary mathematics.

If we take the indefinite integral $\int\frac{\sin(x)}{1+x^8}dx$:

This is also calculated wolfram alpha.
