Today I taught my students about vectors.. well.. quite an abstract concept. However I hope I have made it simple for them by making it looks like "peanuts" and not "mathematics"..
Vectors are simply lines with a certain length (magnitude) and a certain direction (usually indicated by an arrow). To find its magnitude, always try imagining a right angled triangle with the vector as the hypotenuse. I guess it always help to start out by writing the "square root" sign and finding the sum of squares of the x and y components of the vector. Wow! That sounds complicated.. Well at least when I do it on the board, its not that bad..
I always pray that my students will absorb at least 60% of my daily input.. plus they have to carry out and complete the reinforcement exercises which follow all the explanations..
