Q. Given the vector v has an initial point at (8,8) and a terminal point at (8,2), find the exact value of ∥v∥.Answer:
Calculate Differences and Square: To find the magnitude of vector v, we need to calculate the difference in the x-coordinates and the y-coordinates between the terminal point and the initial point. The magnitude of vector v, denoted as ∣∣v∣∣, is given by the formula:∣∣v∣∣=((x2−x1)2+(y2−y1)2)where (x1,y1) is the initial point and (x2,y2) is the terminal point.
Substitute Given Points: Substitute the given points into the formula. The initial point is (8,8) and the terminal point is (8,2). Therefore, x1=8, y1=8, x2=8, and y2=2.∣∣v∣∣=((8−8)2+(2−8)2)
Simplify Squares and Sum: Calculate the differences and square them.∣∣v∣∣=(0)2+(−6)2
Calculate Square Root: Simplify the squares and sum them up.∣∣v∣∣=0+36
Calculate Square Root: Simplify the squares and sum them up.∣∣v∣∣=(0+36)Calculate the square root to find the magnitude.∣∣v∣∣=36∣∣v∣∣=6
