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.
trigonometry: the branch of mathematics that studies the relationships between the sides and the angles of right triangles, and deals with and with the trigonometric functions (sine, cosine, tangent and their reciprocals). trinomial: an algebraic equation with 3 terms, e.g. 3 x + 5 y + 8 z; 3 x 3 + 2 x 2 + x; etc.
