sin((2pi)/4)

Solution

sin (\frac{2 π}{4})

Solution

1

Solution steps

sin (\frac{2 π}{4})

Simplify:

\frac{2 π}{4} = \frac{π}{2}

\frac{2 π}{4}

Cancel the common factor:

2

= \frac{π}{2}

= sin (\frac{π}{2})

Use the following trivial identity:

sin (\frac{π}{2}) = 1

sin (\frac{π}{2})

sin (x)
