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.
Relationships among the inverse trigonometric functions. 1  The usual principal values of the arcsin(x) (red) and arccos(x) (blue) functions graphed on the cartesian plane. 2  The usual principal values of the arctan(x) and arccot(x) functions graphed on the cartesian plane.
