WebName: Period: Date: Math Lab: Trig Identities Hexagon Using the hexagon below, you will create a memory trick to learn the reciprocal, product/quotient, Pythagorean, and … WebThe Pythagorean Identities are based on the properties of a right triangle. cos2θ + sin2θ = 1. 1 + cot2θ = csc2θ. 1 + tan2θ = sec2θ. The even-odd identities relate the value of a trigonometric function at a given angle to the value of the function at the opposite angle. tan(− θ) = − tanθ. cot(− θ) = − cotθ.

WebApr 9, 2024 · Magic Hexagon. A magic hexagon for trigonometric identities of order ‘n’ is an arrangement of numbers in a centered hexagonal pattern having n cells on each edge, such that the numbers in each row, in all the three directions, sum up to the same magic constant. It appears that magic hexagons exist only for n = 1 (that is trivial) and n = 3. WebThere are some trigonometric identities which you must remember in order to simplify trigonometric expressions when required. These are: \[{\sin ^2}x + {\cos ^2}x = 1\] OK, we have now built our hexagon, what do we get out of it? Well, we can now follow "around the clock" (either direction) to get all the "Quotient Identities": See more The hexagon also shows that a function betweenany two functions is equal to them multiplied together (if they are opposite each other, then the "1" is between them): Some … See more You can also get the "Reciprocal Identities", by going "through the 1" Here is the full set: 1. sin(x) = 1 / csc(x) 2. cos(x) = 1 / sec(x) 3. cot(x) = 1 … See more The Unit Circleshows us that sin2 x + cos2x = 1 The magic hexagon can help us remember that, too, by going clockwise around any of these three triangles: And we have: 1. sin2(x) + cos2(x) = 1 2. 1 + cot2(x) = csc2(x) 3. … See more AND we also get these co-function identities: Examples: 1. sin(30°) = cos(60°) 2. tan(80°) = cot(10°) 3. sec(40°) = csc(50°) Or, if you prefer, in radians: Examples: 1. … See more in bed with a highlander audiobook
