Log solver

Although before the advent of calculators, logarithms were not as popular as they are today, logarithms were a very useful mathematical tool when equations for power exponential calculation appeared. By definition, every logarithm has a base a. If x takes the logarithm of a, it will be written as log_ {a} {x}, then the logarithm can also be defined in this way: logarithm is the power exponent of which makes the power of a equal to X. Replace it with a mathematical expression (it says that the thing I haven't worn for a long time is y): It can be seen how stubborn Gong Shuxiang is and how twisted he is! After arriving at the 212 artillery regiment, Gong Shuxiang was assigned to the reconnaissance team of the regiment command company, which was really useful. Artillery reconnaissance is mostly about artillery mirrors, steering wheels and calculators, which are related to trigonometric functions and logarithmic tables learned in high school. In addition, Liu Chunhua, their company commander, is a good hand in military technology, which has trained Gong Shuxiang into a first-class reconnaissance squad leader. The regimental commander's command is mainly based on the reconnaissance and calculation of the reconnaissance squad of the regimental command company. In 1940, Morita came to Boshan with this daily logarithmic ruler. Before the advent of electronic calculators, this kind of double-sided multi-functional slide rule was called analog computers internationally. This slide ruler with a sliding cursor and a walking ruler has accompanied its owner throughout his career as an architect. At that time, the approval of medical expense reimbursement documents had to be entered manually. The agent has three treasures: pen, ruler and calculator. When you get a document, first look at the basic information of the insured, then identify the authenticity of the document one by one, then tap the calculator to calculate the total amount, and then match the logarithm with the insured. In the final stage of preparation for the exam, the author watched a part of modern logic design with the recommendation of other guys. It is recommended that students who take the CS exam at Dongda read it carefully when they have time. If time is tight, they should try to see the explanation of the arithmetic unit. In short, Dongda CS will try its best not to miss any knowledge point in preparing for the digital examination. A calculator that supports photographing calculation: arithmetic, integer, fraction, decimal, root, algebraic expression, linear equation, inequality, univariate quadratic equation or inequality, absolute equation and inequality, equation, logarithm, trigonometric function, exponential function and derivative and integral of logarithmic function. Unlike photo search software such as [a certain industry group], this software can be used without membership and installation. In addition, it should be noted that the number of calculation questions this year is still quite large, and on the admission ticket for the postgraduate examination of Tsinghua University, the unified requirements for the preliminary examination are not allowed to use calculators. Therefore, when doing examples, it is best to exercise your written arithmetic ability. Of course, we don't need to worry too much. The problems requiring written calculation only involve some addition and subtraction methods and simple integration. For exponential and logarithmic operations, you can express them without calculating the specific values. Since 975 has only real questions for nearly three years, students with spare power can also try to do some 838 physical chemistry questions to further understand the teacher's style of writing questions.
