Project 25: Adding Vectors
Intro Problem: Suppose you left your house and first walked 3 miles east and 2 miles south to get to a resting stop. Then you walk 1 miles west and 4 miles north to get to a friends house.
Your friend's house is 2 miles north and 2 miles east of your house.
An example of vector addition is shown above. Vector u = <3, -2> and vector v = <-1, 4>. The sum u + v = <2, 2>. Notice that when tail of the second vector is placed at the tip of the first vector, the result is equal to the sum.
Project 25: Variables 'x1', 'y1', 'x2', and 'y2' have been initialized.
x1 is the x-component of the first vector (3 in the first example)
y1 is the y-component of the first vector (-2 in the first example)
x2 is the x-component of the second vector (-1 in the first example)
y2 is the y-component of the second vector (4 in the first example).
Task: Appropriately initialize the values of 'sumX' and 'sumY' which represent the x and y components of the sum.
Note: The following trig methods are available.
cosine(x)
sine(x)
tangent(x)
cosineInverse(x)
sineInverse(x)
tangentInverse(x)
