Unit 5 part 1

We began unit 5 today and focused the day mainly on vectors in two dimensions. A vector can be defined basically as a quantity with magnitude and direction. They can be illustrated on a piece of paper as a line with a starting point and an arrow. Today, we learned that the sum of two vectors would be the displacement of the distances on a two dimensional surface. We practiced adding vectors on the x and y axes but then moved on the the much more complicated diagonal vectors. We learned to add these vectors by making a right triangle for each diagonal vector and turning them into the hypotenuse for a right triangle. We then found the values for the opposite and adjacent sides of the triangle(s) and found the sum of the x and y values of the axes to be used to make another right triangle. That last set of vectors will form a right triangle where the hypotenuse of that triangle would be the final answer along with angle (data)
