Geometrically, these identities involve certain trigonometric functions (such as sine, cosine, tangent) of one or more angles. Sine, cosine and tangent are the primary trigonometry functions whereas cotangent, secant and cosecant are the other three functions. The trigonometric identities are based on all the six trig functions.

The terms cosine, cotangent and cosecant can be understood by knowing that the prefix “co” refers to “complement.” This is because the values of these co-functions : cos(x) , cot(x) , and csc(x) are equal respectively to the values of: sin(90º - x), tan(90º - x), and sec(90º - x) for their complementary angles.
Nov 19, 2021 · You can see from the paragraphs just above that if c = 1 then a = sin A and b = cos A. In other words, in a unit right triangle the opposite side will equal the sine and the adjacent side will equal the cosine of the angle. The triangle is often drawn in a unit circle, a circle of radius 1, as shown at right.
Oct 6, 2016 · For cosine: The prefix "co-" (in "cosine", "cotangent", "cosecant") is found in Edmund Gunter's Canon triangulorum (1620), which defines the cosinus as an abbreviation for the sinus complementi (sine of the complementary angle) and proceeds to define the cotangens similarly.

Topics Definition of Hebrew Words. The Hebrew word for "sin" is חטאה (hhatah, Strong's #2403) and literally means "miss the mark." From my understanding of the Bible, there are two types of sin, accidental and deliberate. I explain it this way.
