The equations of the given planes are

r.(i^+2j^+3k^)4=0.....(1)r.(2i^+j^k^)+5=0......(2)

The equation of the plane passing through the line intersection of the plane given in equation (1) and equation (2) is

[r.(i^+2j^+3k^)4]+λ[r.(2i^+j^k^)+5]=0r.[(2λ+1)i^+(λ+2)j^+(3λ)k^]+(5λ4)=0.....(3)

The plane in equation (3) is perpendicular to the plane,  r.(5i^+3j^6k^)+8=0

5(2λ+1)+3(λ+2)6(3λ)=019λ7=0λ=719

Substituting λ = 7/19 in equation (3), we obtain

r.(1319i^+4519j^+5019k^)4119=0r.(33i^+45j^+50k^)41=0

This is the vector equation of the required plane.

The Cartesian equation of this plane can be obtained by substituting  r=xi^+yj^+zk^  in equation (3).

(xi^+yj^+zk^).(33i^+45j^+50k^)41=033x+45y+50z41=0

The coordinates of the points, O and P, are (0, 0) and (1, 2, −3) respectively.

Therefore, the direction ratios of OP are (1 − 0) = 1, (2 − 0) = 2, and (−3 − 0) = −3

It is known that the equation of the plane passing through the point (x1,  y1 z1) is

 a (xx1)+b (yy1)+c (zz1)=0 where, a,  b, and c are the direction ratios of normal.

Here, the direction ratios of normal are 1, 2, and −3 and the point P is (1, 2, −3).

Thus, the equation of the required plane is

1 (x1)+2 (y2)3 (z+3)0x+2y3z14=0

Equation of one plane is

r.(i^+j^+k^)=1r.(i^+j^+k^)1=0r.(2i^+3j^k^)+4=0

The equation of any plane passing through the line of intersection of these planes is

[r.(i^+j^+k^)1]+λ[r.(2i^+3j^k^)+4]=0r.[(2λ+1)i^+(3λ+1)j^+(1λ)k^]+(4λ1)=0.....(1)

Its direction ratios are (2λ + 1), (3λ + 1), and (1 − λ).

The required plane is parallel to x-axis. Therefore, its normal is perpendicular to x-axis.

The direction ratios of x-axis are 1, 0, and 0.

1.(2λ+1)+0(3λ+1)+0(1λ)=02λ+1=0λ=12

Substituting λ = -1/2 in equation (1), we obtain

r.[12j^+32k^]+(3)=0r(j^3k^)+6=0

Therefore, its Cartesian equation is y − 3z + 6 = 0

This is the equation of the required plane.

The position vector through the point (1,1, p) is  a1=i^+j^+pk^

Similarly, the position vector through the point (3,0,1) is

a2=4i^+k^

The equation of the given plane is  r.(3i^+4j^12k^)+13=0

It is known that the perpendicular distance between a point whose position vector is  a  and the plane,  r.N=d is given by,  D=|a.Nd||N|

Here, N=3i^+4j^12k^ and  d =13

Therefore, the distance between the point (1, 1, p) and the given plane is

D1=|(i^+j^+pk^).(3i^+4j^12k^)+13||3i^+4j^12k^|D1=|3+412p+13|D1=|2012p|13..........(1)

Similarly, the distance between the point (3,0,1) and the given plane is

D2=|(3i^+k^).(3i^+4j^12k^)+13||3i^+4j^12k^|D1=|912+13|D1=813..........(2)

It is given that the distance between the required plane and the points, (1,1, p)and(3,0,1), is equal.

 D1 = D2

|2012p|13=8132012p=8,or,(2012p)=812p=12,or,12p=28p=1,or,p=73

The equation of the plane passing through the point a (x +1)+ b (y 3)+ c (z 2)=0(1) where, a, b, c are the direction ratios of normal to the plane.

It is known that two planes,  a1x+b1y+c1z+d1=0&a2x+b2y+c2z+d2=0 are perpendicular, if a1a2+b1b2+c1c2=0

Plane (1) is perpendicular to the plane,  x +2y +3z =5

a.1 + b .2 + c.3 = 0a + 2b + 3c = 0         ....(2)

Also, plane (1) is perpendicular to the plane, 3x +3y + z =0

a .3 + b.3 + c.1 = 03a + 3b + c = 0          .....(3)

From equations (2) and (3), we obtain

a2×13×3=b3×31×1=c1×32×3a7=b8=c3=k(say)a=7k,b=8k,c=3k

Substituting the values of a, b, and c in equation (1), we obtain

7k(x+1)+8k(y3)3k(z2)=0(7x7)+(8y24)3z+6=07x+8y3z25=07x8y+3z+25=0

This is the required equation of the plane.

It is known that the equation of the line through the points, (x1, y1, z1)and(x2, y2, z2) , is

xx1x2x1=xy1y2y1=zz1z2z1

Since the line passes through the points, (3,4,5)and(2,3,1) , its equation is given by,

x323=y+43+4=z+51+5x31=y+41=z+56=k(say)x=3k,y=k4,z=6k5

Therefore, any point on the line is of the form (3 k, k 4,6k 5).

This point lies on the plane, 2x + y + z =7

2 (3 k) + (k 4) + (6k 5) = 75k  3 = 7k = 2

Hence, the coordinates of the required point are (32,24,6×25)i.e., (1,2,7).

It is known that the equation of the line passing through the points, (x1, y1, z1)and(x2, y2, z2), is  xx1x2x1=xy1y2y1=zz1z2z1

The line passing through the points, (5,1,6)and(3,4,1), is given by,

x535=y141=z616x52=y13=z65=k(say)x=52k,y=3k+1,z=65k

Any point on the line is of the form (52k,3k +1,65k).

Since the line passes through ZX-plane,

3k+1=0k=1352k=52(13)=17365k=65(13)=233

Therefore, the required point is (173,0,233)

31. L.H.S. = sin 2x + 2 sin 4x + sin 6x

Using sin A + sin B = 2 sin A + B/2 cos A - B/2  we have,

L.H.S. = (sin 2x + sin 6x) + 2 sin 4x

= 2 s i n ( 2 x + 6 x 2 ) c o s ( 2 x 6 x 2 ) + 2 s i n 4 x .

= 2 s i n 8 x 2 c o s ( 4 x 2 ) + 2 s i n 4 x .

= 2 s i n 4 x c o s 2 x + 2 s i n 4 x [ ? c o s ( x ) = x ]

= 2 s i n 4 x [ c o s 2 x + 1 ]

We know that,

cos2x=2cos2x1

cos2x+1=2cos2x

Hence,

L.H.S=2sin4x(2cos2x)

=4cos2xsin4x

= R.H.S

The equation of YZplaneis x =0

Since the line passes through YZ-plane,

52k =0

k=523k+1=3×52+1=17265k=65×52=132

Therefore, the required point is  (0,172,132) .

The given lines are r=6i^+2j^+2k^+λ(i^2j^2k^)..........(1)r=4i^k^+μ(3i^2j^2k^)...........(2) r=6i^+2j^+2k^+λ(i^2j^2k^)..........(1)r=4i^k^+μ(3i^2j^2k^)...........(2)

It is known that the shortest distance between two lines,  r=a1+λb1&r=a2+λb2   is given by

d=|(b1×b2).(a1a2)|b1×b2||

Comparing  r=a1+λb1&r=a2+λb2 to equations (1) and (2), we obtain

a1=6i^+2j^+2k^b1=i^2j^2k^a2=4i^k^b2=3i^2j^2k^

a2a1=(4i^k^)(6i^+2j^+2k^)=10i^2j^3k^

b1×b2=|i^j^k^122322|=(4+4)i^(26)j^+(2+6)k^=8i^+8j^+4k^

|b1×b2|==12(b1×b2).(a2a1)=(8i^+8j^+4k^).(10i^2j^3k^)=801612=108

Substituting all the values in equation (1), we obtain

d=|10812|=9

Therefore, the shortest distance between the two given lines is 9 units.
