1. encrypt the message "boston" with the generalized caesar cipher f(p) ≡ 3(p − 10) mod 26
2. find the decryption function. your work must include the step-by-step process of finding the inverse.
3. use the decryption function to decrypt your earlier answer.
4. repeat the previous 3 questions, but this time use a two character block cipher with f(p) ≡ 707p + 15432 mod 123889

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.
