Compute the gradients of each of the following functions: 0' = .ry: v = In [elm2 rm] r: m = W l/r Note: 0 Remember that your tutorial has Hints in it, at the end of each chapter. If you're stuck, they are often quite useful! 0 If the answer is a scalar, you can just type it in the box (using the Calcpad if you like, or using lfor fractions, " for exponents, shift and - for subscripts, etc,) For multiplication, you can either leave a space, or use '. So 9 tr >0: r = II 2 xi Note that this is not the same as 11' without a space; that will get read as an entirely different variable! - If you need to enter a vector, enter an ordered list of components, so for A you can enter either X: 1A,. A,.A,) = {A,.Ay.A,}l I . l Note that the system isn't great with multiplying through by overall factors, so it's better not to write e.g, i (241' 2Av' 2A1) ' V0: X VL' = VI\" = X
