`50-{13+2(4of4)}`

Let A = {1,2,3,4} and f : A to A satisfy f (1) =2, f(2)=3, f(3)=4, f (4)=1. Suppose g:A to A satisfies g (1) =3 and fog = gof , then g = (a).{(1,3), (2,1), (3,2), (4,4)} (b).{(1,3), (2,4),(3,1),(4,2)} (c).{(1,3),(2,2),(3,4),(4,3)} (d).{(1,3),(2,4),(3,2),(4,1)}

Show that the three lines with direction cosines (12)/13, (-3)/13, (-4)/13 ;(4)/13, (12)/13, (3)/13; (3)/13, (-4)/13, (12)/13 are mutually perpendicular.

13 div{4 of 2 - 3 + 4 xx(6-4)} is equal to: 13 div{4 of 2 - 3 + 4 xx(6-4)} का मान क्या होगा ?

Add the following: 3frac{1}{13} + 1frac{4}{13} + 2frac{3}{13}

Solve (4/13)^4 . (13/7)^2 . (7/4)^3

The vertices A, B, C of a triangle are (2,1),(5,2)and(3,4) , respectively. Then, the circumcentre is a) ((13)/(4),(-9)/(4)) b) ((-13)/(4),(9)/(4)) c) ((-13)/(4),(9)/(4)) d) ((13)/(4),(9)/(4))

Find : a. 4 (5)/(13)- 3 (7)/(13) + 2 (8)/(13)

if A=[{:(4,2),(-3,2),(1,3):}]and B=[{:(-1,3),(0,2),(2,-4):}], then find 3A-4B.

(-4)/(13)+0=0+(-4)/(13)

Show that the three lines with direction cosines quad (12)/(13),(-3)/(13),(-4)/(13),(4)/(13),(12)/(13),(3)/(13);(3)/(13),(-4)/(13),(12)/(13) are mutually perpendicular.
