1 Sprays and grease can leave a residue on non-stick pans that is difficult to remove. 2  Start by mixing water and baking soda to make a paste. 3  Spread the paste on the residue. 4  Scrub the surface with a nylon scrubber.
In mathematics, the inverse trigonometric functions (occasionally called cyclometric functions) are the inverse functions of the trigonometric functions (with suitably restricted domains). Specifically, they are the inverses of the sine, cosine, tangent, cotangent, secant, and cosecant functions.
Inverse function definition. An inverse function is a function that undoes the action of the another function. A function $g$ is the inverse of a function $f$ if whenever $y=f(x)$ then $x=g(y)$. In other words, applying $f$ and then $g$ is the same thing as doing nothing.We can write this in terms of the composition of $f$ and $g$ as $g(f(x))=x$. function $g$ is the inverse of a function $f$ if whenever $y=f(x)$ then $x=g(y)$. In other words, applying $f$ and then $g$ is the same thing as doing nothing.
