One tool that can be used is Letter equation solver. We can help me with math work.

## The Best Letter equation solver

Letter equation solver is a software program that helps students solve math problems. Clem's law There are two preconditions for solving the equations with Clem's law, one is that the number of equations should be equal to the number of unknowns, and the other is that the determinant of the coefficient matrix should not be equal to zero. Solving equations with cram's rule is actually equivalent to solving linear equations with the inverse matrix method, which establishes the relationship between the solution of linear equations and its coefficients and constants. However, since n + 1 n-order determinants need to be calculated when solving, the workload is often very large, so cram's rule is often used in theoretical proof and rarely used for specific solutions. For the 3D problem, its essence is to solve the elastic mechanics problem with 6 independent stress components (shear stress is equal to each other), 6 independent strain components and 3 displacement components. This problem can be solved by simultaneous equilibrium equations (3), geometric equations (6) and physical equations (generalized Hooke's law, 6).

It is necessary to find the rate of the proportion before using the formula of the denominator rate to solve the denominator, that is, the overall rate. Basic formula of growth problem (Solving growth volume, growth rate, base period value, current period value), proportion (basic formula and modification of proportion, growth volume of proportion, judging the rise / fall of proportion), multiple, average (basic formula and modification of average, growth rate of average, judging the rise / fall of average), cross, etc..

The mathematics part is divided into two parts: usable calculators and unusable calculators. It mainly examines algebra, problem solving and data analysis, introduction to higher mathematics, geometry, trigonometry and other related contents. Wherein: IB math exam has strict requirements on the setting of calculators. If the invigilator clears the setting of calculators during the exam, you need to be able to quickly change it to the original mode. Therefore, it is also necessary to spend some time doing calculator exercises.

In tunnel engineering, the surrounding rock condition is usually represented by the surrounding rock classification. At present, many widely used surrounding rock classification methods have been proposed, but the classification methods in different industry standards are still quite different, and the commonly used surrounding rock classification index system is a simple calculation and algebraic superposition of surrounding rock lithology, integrity, geological structure conditions and other indicators, without fully considering the weight of each impact factor. In addition, the advanced geological prediction combined with different geophysical prospecting technologies has become one of the common means of dynamic classification of surrounding rock in tunnels at present. However, the interpretation of detection data in the advanced geological prediction is still mainly carried out manually, which has certain subjectivity and experience.

## Help with math

*THIS IS THE BEST APP! It really made me open my eyes and understand Math! For real! It explains so simple yet so well to understand! There are so many things and it help you just about right away I will totally recommend! I personally had such great time on it and it really damn helped like wow.; -; ^-^ I hope more people get it because it really can help you understand not only solve it but it makes you get the problem and next time even can do it alone! Ha-ha*
