    MathHelper Lite

    MathHelper allows you to solve math exercises and get full steps of sollution

    ATTENTION: Finally! MathHelper opearates on English language (including built-in math reference)!!!

    MathHelper is a unique application for students. The uniqueness of the application is that it allows us to see not only the answer, but a detailed solution of the problem. Now you do not need to order the work in math or ask for help from classmates - assistant in mathematics will do everything himself. In addition to solving problems, the application includes the theory on these topics and a scientific calculator.

    MathHelper Lite allows you to solve a wide range of tasks.
    MathHelper allows you to quickly solve typical mathematical exercises of the linear and vector algebra, devided in 4 sections:

    1. Linear Algebra - Operations with matrices:
    *Matrix transposition
    *Calculate determinant of a Matrix
    *Matrix Inversion
    *Adding and Subtracting Matrices
    *Matrix multiplication
    *Scalar Matrix multiplication
    *Calculate the rank of a Matrix

    2. Linear Algebra - Systems of linear equations:
    *Gauss method
    *Cramer's method
    *By the inverse of the matrix

    3. Vector Algebra - Vectors:
    *Finding the magnitude or length of a Vector
    *Collinearity of two Vectors
    *Orthogonality of vectors
    *Vector Addition, Subtraction and Scalar Multiplication
    *Vector Multiplication
    *Finding the Angle Between two Vectors
    *Finding the cosine of the angle between the vectors AB and AC
    *Finding the projection of one Vector on another
    *Coplanarity of the Vectors

    4. Vector Algebra - Figures:
    *Calculate the area of ​​a triangle
    *Whether the four points lie on one plane
    *Calculate the volume of a tetrahedron (pyramid)
    *Find the volume and height of a tetrahedron (pyramid)
