Studying XML in a DBMS course is important because(a) XML can encapsulate subelements to form objects, so it has the power of OODB.(b) Although XML may be dying, it is not dead yet.(c) XML is a more powerful markup language than HTML.(d) XML is a good example of studying storage and manipulating semi-structured data, and facilitating data exchange in a networked environment. (e) None of the above.

Robots with telescoping arms are sometimes used to perform tasks (e.g., welding or placing screws) where access may be difficult for other robotic types. during a test run, a robot arm is programmed to extend according to the relationship r = 3 + 0.5cos(4θ) and the arm rotates according to the relationship θ=−π4t2+πt , where r is in feet, θ is in radians, and t is in seconds. use a computer program to plot the path of tip a in x and y coordinates for 0 ≤ t ≤ 4s.
