How do you determine how far your vehicle is traveling per second?
If you are actually in your car, check the spedometer. That will tell you your instantaneous velocity; that is, distance traveled per second.If this is a calculus question and you are given the function of your position with respect to time, simply take the derivative of your function and evaluate your derivative at the time at which you would like to determine your instantaneous velocity.Alternatively and more unlikely, you can integrate your acceleration function and solve for your antiderivative based on an initial value given by the context of the problem.
What is the meaning of differential in mathematics?
In mathematics, a differential refers to an infinitesimal change in a variable, often used in the context of calculus. Specifically, it represents the derivative of a function, indicating how the function value changes as its input changes.

What is a gradient in maths terms?
In mathematical terms, a gradient refers to the rate of change of a function with respect to its variables. In the context of a function of several variables, the gradient is a vector that points in the direction of the steepest ascent and whose magnitude represents the rate of increase in that direction. For a function ( f(x, y) ), the gradient is expressed as ( \nabla f = \left( \frac{\partial f}{\partial x}, \frac{\partial f}{\partial y} \right) ). In single-variable calculus, the gradient is simply the derivative of the function.
What is the lowest point on a graph or curve?
The lowest point on a graph or curve is known as the local minimum or global minimum, depending on its context. A local minimum is a point where the function value is lower than that of its immediate neighbors, while a global minimum is the absolute lowest point across the entire graph. This point often represents a minimum value of the function being graphed and can be identified using calculus techniques such as finding the derivative and setting it to zero.
