Let P(e^(i theta_(1))),Q(e^(i theta_(2))) and R(e^(i theta_(3))) be the vertices of a triangle PQR in the Argand Plane.Theorthocenter of the triangle PQR is

P(3, 4), Q(7, -2) and R(-2, -1) are the vertices of triangle PQR. Write down the equation of the median of the triangle through R.

P(3,4), Q(7,2) and R(-2,-1) are the vertices of Delta PQR. Write down the slope of each side of the triangle.

The value of e^(I theta) - e^(-itheta) is …….

If z = re^(itheta) , then abs(e^(iz)) =

If z= 5e^(itheta), then |e^(iz)| is equal to

The base of vertices of an isosceles triangle PQR are Q 1,3 and R -2,7.The vertex p can be :
