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.
1 Inverse: 2  denotes the modular multiplicative inverse, which is defined if and only if and are relatively prime, which is the case when the left hand side is defined: . 3  Distributive: 4  Division (definition): , when the right hand side is defined.
