Percent slope can be converted to degrees by simply taking the arctan, or the inverse of the tangent function, of one-hundredth of the percent slope. Mathematically, the conversion formula is written as: degrees = arctan (percent slope/100).Know More
For any side of a triangle whose percent slope is unknown, it can be calculated from the corresponding values of vertical rise and horizontal distance. Usually, vertical distance is denoted by Y, and the horizontal distance is denoted by X. Find out the values of these two distances.
The percent slope of a line can be calculated from the values of X and Y by using the formula: percent slope = 100 * (Y/X). For example, if both the values of X and Y are equal to two, then the percent slope is: percent slope = 100 * (2/2) = 100.
Convert the percent slope of the line to degrees by using the formula: degrees = arctan (percent slope/100). For example, if the percent slope of a line is 100, then converting it to degrees yields the result: degrees = arctan (100/100) = arctan (1) = 45 degrees.
A number when multiplied by its multiplicative inverse, or its reciprocal, yields a product of one, which is known as the multiplicative identity of a number. All numbers have an inverse with the exception of zero, which cannot be multiplied by any real number to yield a product of one.Full Answer >
A singular matrix, also called degenerate matrix, is a square matrix whose determinant is zero and that doesn't have a matrix inverse. It's rare to come across a singular matrix because a square matrix selected from a continuous uniform distribution on its entries will almost never be singular.Full Answer >
An orthogonal matrix is a square matrix that has a transpose identical to its inverse. The transpose of a matrix is found by swapping each element a(ij) of the matrix with the element a(ji), where i and j denote the row and column of the element, respectively.Full Answer >
The inverse of a two-by-two matrix is another two-by-two matrix that, when multiplied by the original matrix, gives the identity matrix. Gauss-Jordan elimination and LU decomposition are two methods that can be employed to identify the inverse of a matrix.Full Answer >
