Homework Equations
In the question shown the equation is required to be integrated to apply the trapezium rule. However the x(20-x)^1/2 is confusing me somewhat.
The Attempt at a Solution
When I attempt the question the only way I can think of doing it is be multiplying the 'x' onto the '(20-x)^1/2'
But the resultant I get is
(4.47x - x^3/2)
The get 4.47/2x^2 - 2/5x^5/2
Can anyone point me to a worked example of how to deal with a constant and a variable in a squareroot?
My solutions is not giving me the right answers...
