What is equation in closed-form?
An equation is said to be a closed-form solution if it solves a given problem in terms of functions and mathematical operations from a given generally-accepted set. For example, an infinite sum would generally not be considered closed-form.
What is an example of closed-form?
A closed form is an expression that can be computed by applying a fixed number of familiar operations to the arguments. For example, the expression 2 + 4 + … + 2n is not a closed form, but the expression n(n+1) is a closed form. " = a1 +L+an .
What is an open or closed equation?
An open formula is a formula that contains at least one free variable. An open formula does not have a truth value assigned to it, in contrast with a closed formula which constitutes a proposition and thus can have a truth value like true or false.
What is no closed-form solution?
A closed form solution provides an exact answer and one that is not closed form is an approximation, but you can get a non closed form solution as close as to a closed form solution as you want. Sounds counter intuitive, but if you need it more accurate, then just grind out a little bit more computations.
