Marks: +1, -0

If f(Z) is an analytical function and (r, θ) denotes the polar co-ordinates, then:

$\;{∂u}/{∂r} = \;{1}/{r}\;{∂v}/{∂θ }$ and $\;{∂v}/{∂r} = \;{−1}/{r}\;{∂u}/{∂θ }$
$\;{∂u}/{∂r} = \;{−1}/{r}\;{∂v}/{∂θ }$ and $\;{∂u}/{∂r} = \;{1}/{r}\;{∂v}/{∂θ }$
$\;{∂u}/{∂r} = −r\;{∂v}/{∂θ }$ and $\;{∂v}/{∂r} = r\;{∂u}/{∂θ }$
$\;{∂u}/{∂r} = r\;{∂v}/{∂θ }$ and $\;{∂v}/{∂r} = −r\;{∂u}/{∂θ }$
