Derivative of a Vector
Derivative of a Vector
The rate of change of a vector quantity with respect to time. It represents the direction and rate of change of motion of an object.
Component-wise Differentiation
Component-wise Differentiation
The process of finding the derivative of a vector function, which is obtained by taking the derivative of each component of the vector function separately.
dQ/dt
dQ/dt
A mathematical notation used to represent the derivative of a function. It is read as 'dQ/dt' and denotes the rate of change of Q with respect to the variable t.
