Try y=Aebx diffrentiate this (dy/dx = Abebx) and sub into 2dy/dx -5y = 0 to find complementary function. 2Abebx - 5Aebx = 0 2b - 5 = 0 b = 2.5 Find the particul...

First, I would make sure the pupil understands why rationalising fractions is necessary. Then I would acquaint them with the relevant vocabulary so they can express their thought process better...
A fraction a/b consists of a numerator (the part above the bar, a in this example) and a denominator (the part below the bar, b here). In order to add or subtract fractions, we need to make sure the denom...
This can't be integrated directly as y appears in the numerator and denominator. This is an indication that you must integrate by parts. A/y + B/(3y+2) = (3y - 4)/y(3y + 2) A and B must be found. Multiply...
