maths integral question (needs to be done by a computer)

69 Views Asked by At

$$\int_0^\infty \left( 1 - \left(1 - e^{-\frac{2x}{24}}\right)^{11}\left(1 - e^{-\frac{x}{24}}\right)\left(1 - e^{-\frac{x}{72}}\right)^{2}\left(1 - e^{-\frac{2x}{144}}\right)^{2} \right) \ dx$$

Hey Guys!!

  • I have been trying to integrate the above question but cannot do it because it is too long and therefore, needs to be done by a computer (as it over 50+ terms!!!)
  • The problem is that i do not have my computer software which can do it for me so i thought you guys can help me out by doing it.
  • If you have a smarter way, i am all ears.

Thank you so much :)

The integral evaluates to

$$\frac{19179385249735728551550367428216940591727383888374120235641}{80577616728959000543177737840861586668464761577474749000}$$ $$\approx 238.02373448509798.$$

Such computations can usually be carried out on Wolfram Alpha (click here for mobile version).

Alternatively you could try the substitution suggested in the comments ($u=e^{x/144}$).
