A necessary condition is a condition that must be present for an event to occur. A sufficient condition is a condition or set of conditions that will produce the event. A necessary condition must be there, but it alone does not provide sufficient cause for the occurrence of the event.
What is the difference between sufficient and necessary conditions in math?
A sufficient condition guarantees the truth of another condition, but is not necessary for that other condition to happen. A necessary condition is required for something else to happen, but it does not guarantee that the something else happens.
What is the difference between necessary and sufficient conditions examples?
For example, while air is a necessary condition for human life, it is by no means a sufficient condition, i.e. it does not, by itself, i.e. alone, suffice for human life.
What is the difference between necessity and sufficiency?
In general, a necessary condition is one that must be present in order for another condition to occur, while a sufficient condition is one that produces the said condition.

What is the necessary and sufficient condition for stability?
Abstract: The problem of determining the stability of a feedback system in the presence of perturbation is considered. A necessary and sufficient condition under which the perturbed system remains stable is obtained.
What does sufficient mean in math?
In mathematics, a condition that must be satisfied for a statement to be true and without which the statement cannot be true.
What is the necessary and sufficient condition for SHM?
Necessary and sufficient condition for simple harmonic motion. The restoring force must be proportional to the displacement and act opposite to the direction of motion with no drag forces or friction. The frequency of oscillation should not depend on the amplitude.
Is a sufficient condition?
A sufficient condition is a condition or set of conditions that will produce the event. A necessary condition must be there, but it alone does not provide sufficient cause for the occurrence of the event. Only the sufficient grounds can do this. In other words, all of the necessary elements must be there.
