- Homework Statement:
- Find three integrals: ∫ n da, ∫ n dM, ∫ n dx

- Relevant Equations:
- n = ( sin(a) + M^2 ) / ( 1 + x^2 )

I think in the case of "

∫ ( sin(

= ( 1 / ( 1 + x^2 ) ) * ∫ (sin(

= ( 1 / ( 1 + x^2 ) ) * ( -cos(

= ( - cos(a) + (M^2)a ) / ( 1 + x^2 )

Is this the way to go? This is my first time posting on this website, sorry if my script is not clear.

*n*d*a"*you can see the denominator (1+x^2) as a constant, so∫ ( sin(

*a*) + M^2 ) / ( 1 + x^2 ) d*a*= ( 1 / ( 1 + x^2 ) ) * ∫ (sin(

*a*) + M^2 ) d*a*= ( 1 / ( 1 + x^2 ) ) * ( -cos(

*a*) + (M^2)a )= ( - cos(a) + (M^2)a ) / ( 1 + x^2 )
