Question

determine o valor das expressões a seguir

Answer 1

a- x=Sen(180°)+Cos(360°)/Sen(90°)+Sen(360°)

Sen(180°)=0

Cos(360°)=1

Sen(90°)=1

sen(360°)=0

x=0+1/1+0=1

$\boxed{ \textbf{x = 1}}$

b- y=Cos(2π)+Cos(2π)/Sen(π/2)

2π=360°

π/2=90°

Cos(2π)=1

Sen(π/2)=1

y=2.1/1

y=2

$\boxed{ \textbf{y = 2}}$
