Firstly, an algebraic expression of an odd number should be identified, such as 2n+1 or 2n-1. Doing this would also indicate the knowledge that 2n is always an even number, which will be important further...

a=-2, b=2, c=8, d=-8We know d=-8 from the y interception setting x=0 and y=-8For a, b and c we must construct 3 simultaneous equations from the given information x=-2, 1 and 21.) -8a+4b-2c=82.) a+b+c=83.)...

No. In terms of preparation, my best advice is read widely and be passionate. You can't fake passion and that combined with ability is what they look for. They are testing how you think rather than your k...

Example; Let vector v = (2,5,2) and vector u = (1,-2,3),then u · v = [(2 x 1) + (5 x -2) + (2 x 3)] = [2 -10 + 6] = -2 As the workings hopefully make clear in the line above, the general formula for the s...

My advice is to learn in both directions, for translation especially it is vital to have an active vocabulary rather than simply a passive one. Do whatever helps you, post its, reading, using the words in...
