Log equation solver

Functions, equations and inequalities are closely related and mutually transformed. Using the idea of equations, we can solve the analytic formula of functions by the method of undetermined coefficients. By equivalently transforming functions into equations of curves, we can discuss the number of square roots (or the number of zero points of functions) with the help of the image of functions. Because functions and inequalities have close internal relations, inequality is often used as a tool to study the properties of functions, For example, to prove (discuss) the monotonicity of the function and discuss the maximum value of the rain number, when dealing with the problem of constant inequality, it is often necessary to use the constructor to convert the image or property of the function, so as to determine the range of relevant parameters. The mutual transformation between the function and the equation and inequality is not only manifested in the quadratic function and the one-dimensional quadratic equation and the one-dimensional quadratic inequality, that is, the three ones, but also in the exponential function, Logarithmic functions, exponential and logarithmic equations, and exponential and logarithmic inequalities are mainly manifested in the following four aspects in solving problems
