Hace 2 días · In trigonometry, trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables for which both sides of the equality are defined. Geometrically, these are identities involving certain functions of one or more angles. They are distinct from triangle identities, which are ...
Hace 3 días · Under rather general conditions, a periodic function f (x) can be expressed as a sum of sine waves or cosine waves in a Fourier series. Denoting the sine or cosine basis functions by φ k, the expansion of the periodic function f (t) takes the form: = = ().
Hace 2 días · The trigonometric double angle formulas give a relationship between the basic trigonometric functions applied to twice an angle in terms of trigonometric functions of the angle itself. Tips for remembering the following formulas: We can substitute the values \ ( (2x)\) into the sum formulas for \ (\sin\) and \ (\cos.\)
Hace 4 días · Es decir, para un ángulo dado, se expresa como "sen(θ) = cateto opuesto / hipotenusa". Esta función nos da una idea de la proporción entre el lado opuesto al ángulo y la longitud de la hipotenusa.

Hace 4 días · Complete step-by-step answer: The range of a function is the complete set of all possible resulting values of the dependent variable, after we have substituted the domain. The range is the resulting y-values we get after substituting all the possible x-values.
Hace 4 días · a) Find the absolute maximum and minimum values of f(x) = 3 + sec(x) + cos(x) + sin(x) on [0, Ï€] and state where those values occur. b) Evaluate ∫(x* + 6x^2 + 3x - 17)dx. c) Evaluate ∫(cos^2(x) sin(x) + x^(3√7) + 6x^4)dx.
