By solving this differential equation, we can determine the velocity of an object as a function of time, given its acceleration. Unfortunately it is seldom that these equations have solutions that can be expressed in closed form, so it is common to seek approximate solutions by means of numerical methods; nowadays this can usually be achieved . Hence, the period of the motion is given by 2n. Grayscale digital images can be considered as 2D sampled points of a graph of a function u (x, y) where the domain of the function is the area of the image.

Research into students thinking and reasoning is producing fresh insights into establishing and maintaining learning settings where students may develop a profound comprehension of mathematical ideas and procedures, in addition to novel pedagogical tactics. Bernoullis principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in static pressure or a decrease in the fluids potential energy. Differential Equations are of the following types. They can get some credit for describing what their intuition tells them should be the solution if they are sure in their model and get an answer that just does not make sense.
