    Proving (1+n)^n≥ 5/2* n^n- 1/2* n^(n-1) for n≥2 using Binomial Theorem

    I'm confused. Which binomial expansion should I be using for this question and why? Is it binomial expansion for (a+b)^n or (1+x)^n

    Undergrad How to calculate tension in a cable

    Thanks, I do not know an angle as it is only theoretical, but I would like to know how to calculate 90deg to the vertical i.e. directly behind the aircraft and a 30deg below the horizontal

    Undergrad How to calculate tension in a cable

    If an aircraft is flying straight and level and drops a load but it remains attatched to the aircraft by a cable (hung load), how do I calculate the tension in the cable. I know the aircraft speed, the weight og the load and the length of the cable. Thanks
