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.
The General Logarithmic Functions. The natural logarithm function is defined as the inverse of the natural exponential function. So it's perfectly natural to define the general logarithmic function as the inverse of the general exponential function. Consider y = 2, the exponential function of base 2, as graphed in Fig. 5.1. Clearly it's one-to-one, and so has an inverse. This inverse is called the logarithmic function of base 2 or logarithm of base 2, and denoted log 2. Thus if y = 2 then x = log 2 y.
