I am going through circuit analysis studies and many times there will be derivatives and integrals given but yet I somehow dont seen to be able to solve them myself. Like in that page above it says that the derivative of
p= RL/(RT+RL)^2 * vT^2 is dp/dRL= RT - RL/(RT + RL)^3 * vT^2
I tried to derivate it myself with the chain rule but I got
(RT + RL)^-2 -2RL(RT+RL)^-3 which is not right apparently. Can someone point where I made the mistake?
