Vectors are equal if they have the same magnitude and direction regardless of where they are. Triangle ABC is isosceles. X is the midpoint of AB, Y is the midpoint of BC and Z is the midpoint of AC.

right)\) Look at the diagram and imagine going from X to Z. How would you write the path in vectors using only the vectors \(\overrightarrow {XY}\) and \(\overrightarrow {ZY}\)? You could say it ...

Pay special attention to chapters like Probability, Three-Dimensions, and Vectors. Write down the formulas in one place and try to memorize them. Do not try to memorize the Maths questions at all ...
