The y-axis ordinates of A, B and D are sin θ, tan θ and csc θ, respectively, while the x-axis abscissas of A, C and E are cos θ, cot θ and sec θ, respectively. Signs of trigonometric functions in each quadrant. Mnemonics like "all students take calculus" indicates when sine, cosine, and tangent are positive from quadrants I to IV. [8]
Germán Genaro Cipriano Teodoro Gómez Valdés y Castillo (19 September 1915 – 29 June 1973), known professionally as Tin-Tan, was a Mexican actor, singer and comedian who was born in Mexico City but was raised and began his career in Ciudad Juarez, Chihuahua.
The tangent half-angle substitution relates an angle to the slope of a line. Introducing a new variable = , sines and cosines can be expressed as rational functions of , and can be expressed as the product of and a rational function of , as follows: = +, = +, = +.
Tan (たん) is intended as an even cuter [6] or affectionate variant of -chan. It evokes a small child's mispronunciation of that form of address, or baby talk – similar to how, for example, a speaker of English might use "widdle" instead of "little" when speaking to a baby.
Thus each of these angles has a rational value for its half-angle tangent, using tan φ/2 = sin φ / (1 + cos φ). The reverse is also true. If there are two positive angles that sum to 90°, each with a rational half-angle tangent, and the third angle is a right angle then a triangle with these interior angles can be scaled to a Pythagorean ...

Both Portuguese and Brazilian nobility adopted the term grande ("grandee") from the Spanish, to designate a higher rank of noblemen. [19] The Brazilian system automatically deemed dukes, marquises and counts (as well as archbishops and bishops) grandes do Império ("grandees of the Empire", or literally translated as "Great Ones of the Empire").
