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.
Right Triangle Definition. To define the trigonometric functions of an angle theta assign one of the angles in a right triangle that value. The functions sine, cosine, and tangent can all be defined by using properties of a right triangle. A right triangle has one angle that is 90 degrees. The longest side of the triangle is the hypotenuse. The side opposite theta will be referred to as opposite. The other side next to theta will be referred to as adjacent.
