What is the degree of a quadratic function?
A quadratic function will have a degree of two.
What are the conditions for error to be minimum in least squares approximation?
Let's start with a first degree polynomial equation:This is a line with slope a. We know that a line will connect any two points. So, a first degree polynomial equation is an exact fit through any two points with distinct x coordinates.If we increase the order of the equation to a second degree polynomial, we get:This will exactly fit a simple curve to three points.If we increase the order of the equation to a third degree polynomial, we get:This will exactly fit four points.if we have more than n + 1 constraints (n being the degree of the polynomial), we can still run the polynomial curve through those constraints. An exact fit to all constraints is not certain (but might happen, for example, in the case of a first degree polynomial exactly fitting three collinear points). In general, however, some method is then needed to evaluate each approximation. The least squares method is one way to compare the deviations.
How do you know that a rhombus has two 80 degree and two 100 degree angels?
First you see how many sides and angels it has
Do you say ' two degrees Celsius ' or ' two degree Celsius '?
Since it's more than one degree, it's plural, therefore it would be "degrees". If it were one degree, then you would say "one degree Celsius".
