сЕКъДА 91 - A Circle is a plane figure bounded by a curved line every point of which is equally distant from a point within called the center.
сЕКъДА 534 - Multiply the divisor, thus augmented, by the last figure of the root, and subtract the product from the dividend, and to the remainder bring down the next period for a new dividend.
сЕКъДА 7 - A sphere is a solid bounded by a curved surface, every point of which is equally distant from a point within called the center.
сЕКъДА 281 - If two triangles have the three sides of the one equal to the three sides of the other, each to each, the triangles are congruent.
сЕКъДА 472 - Three lines are in harmonical proportion, when the first is to the third, as the difference between the first and second, is to the difference between the second and third ; and the second is called a harmonic mean between the first and third. The expression 'harmonical proportion...
сЕКъДА 86 - Then multiply the second and third terms together, and divide the product by the first term: the quotient will be the fourth term, or answer.
сЕКъДА 4 - This cyclopaedia of mathematical science defines, with completeness, precision, and accuracy, every technical term ; thus constituting a popular treatise on each branch and a general view of the whole subject. 50 The National Teachers
сЕКъДА 281 - If two triangles have two sides, and the included angle of the one equal to two sides and the included angle of the other, they are equal in all their parts.
сЕКъДА 480 - In any quadrilateral the sum of the squares of the four sides is equal to the sum of the squares of the diagonals, plus four times the square of the line joining the middle points of the diagonals.
сЕКъДА 140 - Subtract the cube of this number from the first period, and to the remainder bring down the first figure of the next period for a dividend.
