HELP FILLING IN BLANKS IN THE PROCEDURE. Procedure 4: Adding Vectors Graphically If you use a ruler and a protractor to draw a series of vectors to scale, the resultant will run from the beginning of the first vector to the end of the last vector.  In the picture below, measure the lengths and angles of vectors A, B and C and record these in the 2nd and 3rd columns on the datasheet. Remember to measure angles CCW from the positive x axis. Using cos and sin, calculate the x and y components of vectors A, B and C and record these in the last two columns on the datasheet. Add the x components in the next-to-last column and the y-components in the last column  Use Pythagorean Theorem and ArcTan to calculate the magnitude and direction of R Measure the length and angle of vector R Confirm that these two measurements of R match   "Fixing the angle" After you do the "four step method" to add vectors, you sometimes have to "fix the angle". Remember that we always start…
