WebMar 24, 2024 · A univariate function f(x) is said to be even provided that f(x)=f(-x). Geometrically, such functions are symmetric about the y-axis. Examples of even functions include 1 (or, in general, any constant … WebEven function definition. Even functions are functions that return the same expression for both x and -x. This means that if f(x) is an even function when f(-x) = f(x). An even …

WebSep 19, 2013 · Performance. val evaluates when defined. def evaluates on every call, so performance could be worse than val for multiple calls. You'll get the same performance with a single call. And with no calls you'll get no overhead from def, so you can define it even if you will not use it in some branches. WebSince is an even function, rewrite as . Step 2. A function is even if .
