Forex indicators are one way of examining market data. One of the best methods is using approximations of quadratic curves. For example, the Parabolic SAR indicator is an indicator that approximates the trend by a parabola. Of course, not all indicators necessarily map the direction of the trading trend with a curve. But discovering a clear curved path for the trading trend is definitely the dream of many great analysts. The problem that we are dealing with here is actually trying to generalize the idea of approximating the direction of the trading process by using hyperbolic functions. Suppose there are two fixed points in the movement of the financial market and the path length between these two points is also a fixed number, using numerical approximation methods, we try to calculate the maximum and minimum amount of financial market movement. The main idea that is in our minds is the approximation of financial market trends by using hyperbolic functions. We approximate the path between these two points with a hyperbolic sine function. Finally, we try to find the maximum or minimum points of this hyperbolic sine function numerically. پرونده مقاله

Depreciation is a measure of the durability of a fixed asset and refers to the ongoing decline in the quality, quantity, or value of an asset. In fact, over time, the efficiency of fixed assets that are constantly used in business will decrease. Therefore, depreciation can be considered as a kind of price reduction that will still occur even if the goods are properly stored and used properly. For example, no matter how well you maintain your property and take all necessary steps to maintain it properly, over time, you will see water pipes, appliances, etc. wear out. Note that depreciation does not mean erosion and destruction of an asset. Sometimes the costs of depreciating assets are repeated many times in the production process. We intend to present an optimization formula for a specific type of capital depreciation by presenting a mathematical model. Suppose the distance between two cities in a desert is a miles. On one side of the desert is a refinery and on the other side is an industrial factory that requires fuel produced by the refinery for production. N liters of fuel must be sent to this factory. A fuel carrier car is supposed to transport the fuel required by the industrial factory from the refinery. The capacity of this car is z liters. Suppose this car consumes one liter of fuel per mile. Assume that f(z,N,a) is equal to the maximum amount of fuel delivered by this vehicle to the industrial factory, then, when R=N+z-z⌈N/z⌉: پرونده مقاله
