Distinguish following function two methods, first multiply out brackets and distinguish, and second use product rule, then multiply out brackets. Check that you get same result both times.
a) y = (2x3 + 5) (3 + 4x - x2)
b) y = ln (3x3 - 4)
c) y = (2x1/2 + 3x)(4x2 + 3)2
d) y = (3x - 4) / (x + 3)
e) y = ln [(2x2 - 3) /(4x + 5)]
Write thorough calculations to understand how you did it and not just answers.
