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.
Equivalent to the right-triangle definitions, the trigonometric functions can also be defined in terms of the rise, run, and slope of a line segment relative to horizontal. The slope is commonly taught as rise over run or rise / run. The three main trigonometric functions are commonly taught in the order sine, cosine, tangent.
