Is the derivative of y zero?

Is the derivative of y zero?

The derivative represents the change of a function at any given time. The constant never changes—it is constant. Thus, the derivative will always be 0 .

Is the derivative of Infinity 0?

As an infinity is also kind of constant and we know that derivative of any constant is zero. So yes answer is zero.

Is 0 part of the Y axis?

Likewise, the y-intercept is a point at which a graph intercepts the y-axis. The y-coordinate of an x-intercept is always 0, and the x-coordinate of a y-intercept is always 0.

What does it mean if a derivative is infinite?

Geometrically, the tangent line to the graph at that point is vertical. Derivative infinity means that the function grows, derivative negative infinity means that the function goes down.

How do you find the derivative of infinity?

Calculus Examples Since ∞ is constant with respect to x , the derivative of ∞ with respect to x is 0 .

Where are the y-axis?

A y-axis is the vertical axis on the Cartesian coordinate plane. The y-axis starts at negative infinity and increases to positive infinity. The y-axis is also the starting, or 0 point, for measuring how far a point extends horizontally on a graph.

What is the rule for Y 0?

Reflection in the line y = 0 i.e., in the x-axis. The line y = 0 means the x-axis. Let P be a point whose coordinates are (x, y). Let the image of P be P’ in the axis.

What is the limit of the derivative of a function at infinity?

If limit of f at infinity equals 0 then the limit of its derivative f’ at infinity is also zero. An example (which must be pretty tedious for presenting briefly in this thread) is in preparation. The zero limit has no effect on the derivative. Take f (t):= \\sin (t^2).t^ {-1}.

Is X → ∞ a vanishing function?

Taking the derivative of the latter function with respect to x, one observes that, for the values of the parameters as specified, it is indeed vanishing as x → ∞ . □ The answer by Behnam Farid gives only an example of a function of bounded variation which possesses the derivative approachin zero.

Is the function continuous at zero and Infinity?

Well, the function is not continuous at zero, but it doesn’t matter for its behavior at infinity (just replace it by an appropriate constant or such on an appropriate neighborhood of 0 so that f and f’ are continuous). Constant sign on some (t,\\infty) would help, of course, then f is monotonous on (t,\\infty) and you are fine.

Does bounded variation ensure limit zero for the derivative of a function?

The right answer is that even bounded variation does not ensure the limit zero for the derivative! The following example is a function with continuous derivative and can be simply changed to a function wchich is even C^ {\\infty}:
