I think what David meant is that if you want help with working out errors in
a homework problem, then you need to post the work you have done so far.

You won't get good answers from "My problem is to calculate x from y by
using steps one two and three-- please show me how" but you may get answers
from "I am trying to calculate x from y using Fisher's Test for Funkiness
but I'm stuck when I try to calculate the coefficient of crumple.  My code
below attempts to calculate crumple by integrating the doohicky distribution
over the range -1 to 1 but R is throwing a wobbly when I use integrate(). 
Is there something I am doing wrong?"

In other words, if you are getting frustrated by errors then you need to
show us what you are doing and what kind of errors you are getting.
