If `Delta = {:|(1,a),(1,b)|`, then minor of 'b' is ……….

If Delta={:|(1,2,3),(2,0,1),(5,3,8)| , write the minor of the element a_22

If Delta={:|(1,2,3),(2,0,1),(5,3,8)| , write the minor of the element a_21

If Delta= {:|(5,3,8),(2,0,1),(1,2,3)| , write the minor of the element a_23

If Delta= {:|(0,b-a,c-a),(a-b,0,c-b),(a-c,b-c,0)| , then show that Delta is equal to zero.

In Delta ABC, a=5, b=4, c=3. G is the centroid of triangle. If R_(1) be the circum radius of triangle GAB then the value of (a)/(65) R_(1)^(2) must be

If G is the centroid of Delta ABC and G' is the centroid of Delta A' B' C' " then " vec(A A)' + vec(B B)' + vec(C C)' =

Minor of 'd' in determinant {:|(a,c),(b,d)| is……….

In Delta ABC , the ratio a/sin A=b/sinB=c/sinC is not always equal to (All symbols used have usual meaning in a triangle.) a. 2R, where R is the circumradius b. (abc)/(2Delta), where Delta is the area of the triangle c. 2/3 (a^(2)+ b^(2) +c^(2)) ^(1/2) d. ((abc)^(2/3))/((h_(1)h_(2) h_(3))^(1/3)

If the area of the triangle formed by the points (2a,b), (a+b, 2b+a) and (2b, 2a) be Delta_(1) and the area of the triangle whose vertices are (a+b, a-b), (3b-a, b+3a) and (3a-b, 3b-a) be Delta_(2) , then the value of Delta_(2)//Delta_(1) is

if a and b between 0 and 1 such that the points (a, 1). (1, b) and (0, O) from If 'a' and 'b' are real numbers an equilateral triangle then the values of 'a' and 'b' respectively
