Quantities that have magnitude and direction but not position. Some examples of vectors are velocity, displacement, acceleration, and force. They are sometimes called Euclidean or spatial vectors.
2. Write an inline function that returns the value of the function

f(t, x) = sin(Va t) cos (Tx)
and also works for vectors. Test your function by plotting it over the region [0, 5] × [0, 5]. '
