uhh ... is this a "test" for us to do to see if we can beat the set time limit?
If it is for you to complete, have you made any attempt on any of these six problems?
btw, looks like #6 has a typo ... one of those two equal signs is maybe a plus sign?

The first two problems ask you to find the derivative using the "delta process". Do you know what that is?
The next two problem asks you to find the derivative "using the basic differentiation formulas". Do you know what those are?
The fifth problem asks you to find the derivative "using the chain rule". Do you know what that is?

Hello!
I tried to calculate projections of curl using rotation of coordinate system but I encountered with following problem.
Given:
##rot_xA=\frac{\partial A_z}{\partial y}-\frac{\partial A_y}{\partial z}=0##
##rot_yA=\frac{\partial A_x}{\partial z}-\frac{\partial A_z}{\partial x}=1##
##rot_zA=\frac{\partial A_y}{\partial x}-\frac{\partial A_x}{\partial y}=0##
I rotated ##yz##-plane of this coordinate system by an angle ##45## degrees about ##x##-axis and used rotation matrix to...
