Vastringue Concave. A real valued function on an interval or more generally a convex set in vector space is said to be. A concave function is also synonymously called concave downwards concave down convex upwards convex cap or upper convex definition.
F 1 λ x λ x. Let s make a formula for that. Take any two different values a and b in the interval we are looking at.
Let s make a formula for that.
A negative sign means concave down. Usually our task is to find where a curve is concave upward or concave downward. Similar to the narrow wire concave in overall design the wide wire concave is equipped with wires perpendicular to the strong cross bars but at a wider gap to allow more space for larger material to be threshed and for the larger grain to make its way down through the concave without plugging. Then according to the definition the function f is concave if and only if for every pair of numbers a and b with x1 a x2 and x1 b x2 we have.
