Consider a particle that is moving along the space curve given by r1(t) = t3i + (3 − t)j + 2t2k. Write a vector-valued function r2 for a particle that moves four times as fast as the particle represented by r1. Explain how you found the function.
Vector Arithmetic
Vectors are those objects which have a magnitude along with the direction. In vector arithmetic, we will see how arithmetic operators like addition and multiplication are used on any two vectors. Arithmetic in basic means dealing with numbers. Here, magnitude means the length or the size of an object. The notation used is the arrow over the head of the vector indicating its direction.
Vector Calculus
Vector calculus is an important branch of mathematics and it relates two important branches of mathematics namely vector and calculus.
Consider a particle that is moving along the space curve given by r1(t) = t3i + (3 − t)j + 2t2k. Write a
