Explanation Given information: Let the barycentric coordinates are ( r , s , t ). [ a ˜ b ˜ c ˜ ] [ r s t ] = p ˜ Explanation: Cramer’s Rule: Let A be an invertible n × n matrix. For any b in ℝ n , the unique solution of x of A x = b entries are represented by, x i = det A i ( b ) det A Calculation: Represent the coordinates as follows: [ a ˜ b ˜ c ˜ ] [ r s t ] = p ˜ Apply Cramer’s rule to represent the coordinates as follows: r = det [ p ˜ b ˜ c ˜ ] det [ a ˜ b ˜ c ˜ ] Consider the matrix a as a = [ a 1 a 2 ] , b is b = [ b 1 b 2 ] and c is c = [ c 1 c 2 ] Find the determinant of [ a → b → c → ] as follows: det = | 1 1 1 a 1 b 1 c 1 a 2 b 2 c 2 | = − det | a 1 b 1 c 1 1 1 1 a 2 b 2 c 2 | = −
