Deriving my ass

Edit:
- At 51:00 a) is supposed to be 5*d/dx[x^3]+7*d/dx[x^2]-1d/dx[x] (x^2-x are calculated separately)
- At 54:00 b) is supposed to be 4e^x + 8/x (I forgot to multiply the 1/x by 8).
- At 1:00:43 b) techically uses z as the variable for the function, and the x value is a such treated as a constant and every derivation would produce the value 0 (h'(z) = 0). However, if we imagine that the symbols were correct, then everything would be fine.
- At 1:16:00 b) is wrong, the interval is [0,4] (0 to 4, both included). The equation is also simplified to 3z(z-4), which indeed gives us the values 0 and 4 for our interval.
