i) We must differentiate the equation and set it equal to 0 to find stationery points: dy/dx = 3x2 + 6x + 24=0 Note we can take out a factor of 3 x2+ 2x - 8=0 Fact...
Using the table of standard derivatives given at the beginning of the Higher Paper we have, for f(x) = sin(ax), f'(x) = a * cos (ax)and so with this we have, g(x) = 4 * sin(3x), g'(x) = 4 * 3...
Using either polynomial long division or by inspection, the equation can be reduced to:(x-1)(x2+5x+6)The other bracket can the be factored out using inspection or the quadratic formula to...
So the first part of this question is regarding your knowledge and understanding on the subject matter. You should know that for real and equal roots, (b2 - 4ac)=0. (For real and unequal roots,...
