Question

16. Si: f(x) = senx + cos2x + tg4x
Calcular:
$f( \frac{\pi}{2} )$
​

Answer 1

Respuesta:

cero

Explicación paso a paso:

Si: f(x) = senx + cos2x + tg4x

Calcular:

f(π/2) = sen(π/2) + cos2(π/2) + tg4(π/2)

f(π/2) = 1 + cosπ + tg4(π/2)

f(π/2) = 1 - 1 + tg4(π/2)

f(π/2) = 1 - 1 + tg2π

f(π/2) = 1 - 1 + 0

f(π/2) = 0
