An upside-down triangle is a polygon. A polygon is a figure with at least three straight sides or angles. A triangle has three sides, so it would be classified as a polygon.

Your question asks if an upside-down triangle is a polygon. It is, because it is just upside-down, it is still a triangle. The placement of the shape or the way the shape is facing does not effect it's classification as a polygon.

Find the differential of the function w=xsin(2yz^4).

The differential of

$w = x \sin(2yz^4)$

$\mathrm dw = \dfrac{\partial w}{\partial x}\,\mathrm dx + \dfrac{\partial w}{\partial y}\,\mathrm dy + \dfrac{\partial w}{\partial z}\,\mathrm dz$

where the partial derivatives are

$\dfrac{\partial w}{\partial x} = \sin(2yz^4) \\\\ \dfrac{\partial w}{\partial y} = x \cos(2yz^4) \times 2z^4 = 2xz^4 \cos(2yz^4) \\\\ \dfrac{\partial w}{\partial z} = x \cos(2yz^4) \times 8yz^3 = 8xyz^3 \cos(2yz^4)$
