I don't understand

Map of LAND Compute the gradients of each of the following functions; p = xy: = In [=(12 - y?)-1/2] r = 171 = v.x2+ y?+=2 1/r Note: Remember that your tutorial has Hints in it, at the end of each chapter. If you're stuck they are often quite usefull . If the answer is a scalar, you can just type it in the box (using the Calspad if you like, or using / for fractions, " for exponents, shift and - for subscripts, etc ) For multiplication, you can either leave a space, or use . So Note that this is not the same as ax without a space, that will got read as an entirely different variablel . If you need to enter a vector, enter an ordered list of components, so for A you can enter either A = (A,, Ay, Az) = (A,, Ay A). Note that the system isn't great with multiplying through by overall factors, so it's better not to write c.g. $ (2A, 2A, 2A,). 4 Vo = vi + xi X X Vr =
