    Mathematics: Post your doubts here!

    its simple OP is actually the normal to the required plane.. coaz it says that AB is on the plane and OP is perpendicular to the plane. simply use r.n = a.n ( take OA or OB in place of a) (x,y,z) x (2/3,5/3,7/3) = (1,2,2) x (2/3,5/3,7/3) 2x + 5y + 7z = 26

    (ii) |wz| = |w||z| = (1)(R) = R arg|wz| = arg|w| + arg|z| = 2π/3 + θ |z/w| = |z|/|w| = R/1 = R arg|z/w| = arg|z| - arg|w| = θ - 2π/3 (iii) Modulus of all three are same meaning their lengths are equal ( = R) All angles subtended are π/3 (iv) z = 4 +2i The other two vertices are zw and z/w zw...

    he normal to each plane is <2, -1, -3> and <1, 2, 2> respectively. To get the angle between the planes, consider the angle between the normals. To get the equation of the line of intersection, consider the cross product of the normals. This will give you the direction numbers for the line...

    Mathematics: Post your doubts here!

    I hope you can do part (i) because that's just understanding what a complex conjugate is. (ii) |z - 10i| = 2|z - 4i| You are told to square both sides. Question (i) tells you how to do this: |z - ki|^2 = (z - ki)(z* + ki). (z - 10i)(z* + 10i) = 4(z - 4i)(z* + 4i) Simplify to get 0 = zz*...
