Given f ( x ) = sin x and g ( x ) = cos x , show that f ( g ( π 2 ) ) = 0 . Show all your steps.

Giving 100 points, and brainliest to the right answer!!

Respuesta :

  • g(x)=cosx

g(π/2)}

[tex]\\ \rm\rightarrowtail cos(\pi/2)[/tex]

[tex]\\ \rm\rightarrowtail cos 90[/tex]

[tex]\\ \rm\rightarrowtail 0[/tex]

Now

  • f(x)=sinx

f(0)

[tex]\\ \rm\rightarrowtail sin 0[/tex]

[tex]\\ \rm\rightarrowtail Proved [/tex]
