cos(-1/2 pi)

Solution

cos (- \frac{1}{2} π)

Solution

0

Solution steps

cos (- \frac{1}{2} π)

Simplify:

- \frac{1}{2} π = - \frac{π}{2}

= cos (- \frac{π}{2})

Use the following property:

cos (- x) = cos (x)

cos (- \frac{π}{2}) = cos (\frac{π}{2})

= cos (\frac{π}{2})

Use the following trivial identity:

cos (\frac{π}{2}) = 0

= 0
