Two friends Seema and Aditya work in the same office at Delhi. In the Christmas vacations, both decided to go to their hometowns represented by Town A and Town B respectively in the figure given below. Town A and Town B are connected by trains from the same station C (in the given figure)in Delhi.Based on the given situation, answer the following questions: img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/MATH_041_X_SQP_E03_007_Q01.png" width="80%"gt (i) Who will travel more distance, Seema or Aditya, to reach to their hometown? (ii) Seema and Aditya planned to meet at a location D situated at a point D represented by the mid-point of the line joining the points represented by Town A and Town B. Find the coordinates of the point represented by the point D . (iii) Find the area of the triangle formed by joining the points represented by A, B and C.

Point A lies on the curve y = e^(x^2) and has the coordinate (x,e^(-x^2)) where x>0. Point B has the coordinates (x, 0). If 'O' is the origin, then the maximum area of the DeltaAOB is

    The position of a point in a two dimensional plane in Cartesian coordinates is represented by an ordered pair. Accordingly the ordered pairs (1,3), (2,4), (2,3) and (3,2) represents different points in a plane.

    Convert the following points from polar coordinates to the corresponding Cartesian coordinates. (i) (2,pi//3) (ii) (0.pi//2) (iii) (-sqrt(2),pi//4)

    In the DeltaABC , the coordinates of B are (0, 0), AB=2, /_ABC=pi/3 and the middle point of BC has the coordinates (2,0). The centroid of the triangle is
