WebAl finalizar la unidad, el alumno será capaz de : • Reconocer las identidades auxiliares. • Aplicar las identidades trigonométricas a situaciones problemáticas como simplificaciones. PREGUNTA 1 : Si: senx cosx = 2. Calcule: tgx + ctgx. A) 1/3. B) 4. WebRespuesta: La letra E. Explicación paso a paso: tg 20 = ctg 20. tg 20 = 1 / tg 20 ... lo cual no es correcto (ejemplo 4 npnes igual a 1 / 4)

Let’s input value 45 in the form and we will get these results: Radians. Function: Value: Function: Value: Sine (Sin) 0.8509: Conventionally, an abbreviation of each trigonometric function's name is used as its symbol in formulas. Today, the most common versions of these abbreviations are "sin" for sine, "cos" for cosine, "tan" or "tg" for tangent, "sec" for secant, "csc" or "cosec" for cosecant, and "cot" or "ctg" for cotangent. … See more In mathematics, the trigonometric functions (also called circular functions, angle functions or goniometric functions ) are real functions which relate an angle of a right-angled triangle to ratios of two side lengths. They are widely … See more In geometric applications, the argument of a trigonometric function is generally the measure of an angle. For this purpose, any angular unit is … See more The algebraic expressions for the most important angles are as follows: $${\displaystyle \sin 0=\sin 0^{\circ }\quad ={\frac {\sqrt {0}}{2}}=0}$$ (zero angle) $${\displaystyle \sin {\frac {\pi }{6}}=\sin 30^{\circ }={\frac {\sqrt {1}}{2}}={\frac {1}{2}}}$$ See more If the acute angle θ is given, then any right triangles that have an angle of θ are similar to each other. This means that the ratio of any two side lengths depends only on θ. Thus these six … See more The six trigonometric functions can be defined as coordinate values of points on the Euclidean plane that are related to the unit circle, … See more The modern trend in mathematics is to build geometry from calculus rather than the converse. Therefore, except at a very elementary level, … See more Many identities interrelate the trigonometric functions. This section contains the most basic ones; for more identities, see List of trigonometric identities. … See more WebSimplificar a la función más simple: ( Cos((x-y)/2))/(Tan x/2+Ctg y/2) A) Cos x/2 Sen y/2 B) Cos x/2 Sen x/2 C) Tan y/2 D) en x/2 Cos y/2 E) (Cos x)/(Sen y) 5. ...
