Document Summary

Cs 115 sos review package midterm (define x 4) (define x 5) (define x 5) (define (f x) (* x x)) (define (g y z)(* (+ y z)(* y y))) Dylan schnute (tutor) dylan. schnute367@gmail. com. Erin vanderstoep (coordinator) evanders@uwaterloo. ca. General format: (define (function_name parameter1 parameter2 )(function_expression)) Ex. (define v (* 4 2 x)) ; if we type in v, we would get 32. Rules when defining constants: you cannot define the same variable name twice, scheme keeps track of variables. A step by step simplification of a scheme function by applying substitution rules. Remember to take one step at a time. Example 1: (define (square x y)(+ (* x x) (* y y))) Using the above definition, trace: > (+ (* 3 3) (* 12 12)) ; substitute all parameters into the function at once. The design recipe is a key component of cs 115. If the function squarepower takes in a number and squares it, write:
