Question

considerando f(x) = sen x e g(x)= cos x. calcule f(pi/2) + g(pi/6)
a) 1/2
b) √2/2
c) (√2+√3)/2
d) √3/2

Answer 1

Oie, tudo bom?

Resposta: nenhuma das alternativas.

$f(x) = \sin(x) \: \: \: g(x) = \cos(x) \\ f( \frac{\pi}{2} ) +g( \frac{\pi}{6} )$

$= \sin( \frac{\pi}{2} ) + \cos( \frac{\pi}{6} ) \\ \boxed{ = 1 + \frac{ \sqrt{3} }{2} }$
