... The y-intercept of a function is the value of y at which the graph of the function crosses the y-axis, or the value of y when x equals 0. When analyzing the y-intercept in a real-world context, this is the starting value of whatever is represented by the y-axis. For example, if the x-axis represents ...

To solve the system of linear congruences of two variables 13x + 2y ≡ 1 (mod 15), 10x + 9y ≡ 8 (mod 15), the idea is (similar to the linear algebra in solving linear equations) to eliminate one variable, say y. To do so, one naturally wants to multiply 9 on the both sides of the first equation a ...

Calculus of variations

Calculus of variations is a field of mathematical analysis that deals with maximizing or minimizing functionals, which are mappings from a set of functions to the real numbers. Functionals are often expressed as definite integrals involving functions and their derivatives. The interest is in extremal functions that make the functional attain a maximum or minimum value – or stationary functions – those where the rate of change of the functional is zero.A simple example of such a problem is to find the curve of shortest length connecting two points. If there are no constraints, the solution is obviously a straight line between the points. However, if the curve is constrained to lie on a surface in space, then the solution is less obvious, and possibly many solutions may exist. Such solutions are known as geodesics. A related problem is posed by Fermat's principle: light follows the path of shortest optical length connecting two points, where the optical length depends upon the material of the medium. One corresponding concept in mechanics is the principle of least action.Many important problems involve functions of several variables. Solutions of boundary value problems for the Laplace equation satisfy the Dirichlet principle. Plateau's problem requires finding a surface of minimal area that spans a given contour in space: a solution can often be found by dipping a frame in a solution of soap suds. Although such experiments are relatively easy to perform, their mathematical interpretation is far from simple: there may be more than one locally minimizing surface, and they may have non-trivial topology.
