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.

Assume that you have an sorted array of records. assume that the length of the array (n) is known. give two different methods to search for a specific value in this array. you can use english or pseudo-code for your algorithm. what is the time complexity for each algorithm and why?
