Let A = (5,– 1,1)
B = (7,– 4, 7)
C = (1, – 6, 10)
D = (– 1, – 3, 4)
Then the position vectors of A,B,C,D are
∴ ABCD forms a Rhombus.

5×2+0×5+8×0+9+8
= 10+0×5+8×0+9+8
= 10 +8×0+9 + 8
= 10 + 9 + 8
= 19 + 8

7, 77, 777, 7777 ….to n terms.
Sn=7+77+777+7777+……+to n terms
introducing 9
= (7/9) [9+99+999+……+ to n terms]
= (7/9) [(10-1) + (100-1) + (1000-1) +……...+ to n term]
= (7/9) [10+100+1000+……... n terms – (1+1+1+1+…… n terms)
= (7/9) [10+100+1000+………n terms –n]
Here a=10, r=10
= (7/9) [10(10n-1)/ (9) - n]

R = {(x, x3): x is a prime number less than 10}
The prime numbers less than 10 are 2, 3, 5, and 7.
∴R = {(2, 8), (3, 27), (5, 125), (7, 343)}

sin 100° + cos 100°
= sin100° + cos(90°+10°)
[cos 10° becomes sin 10°]
= sin100° + sin 10°
by the formula,
sin C + sin D = 2cos sin
= 2cos sin
= 2cos sin
= 2cos55° + sin45°
= 2cos55° + 1/√2
=√2.√2 cos55° .1/√2
= √2cos55°
