Need Help with Mech Engineering Lab. Finding Error propagation for uncertainty in electrical Lab using Voltage Divider, Oscilloscope, Digital Multimeter, and a signal generator.

I need help Finding the Error propagation in order to determine the Uncertainty in this experiment. I realize it's a lot but I just need help with the part circled in red, or if it's easier to use the equations directly below that. The rest of the post is just to assist whoever can help me. I don't think it's 100% required for help. ​ The lab was broken up into 3 different sections. The first part of the lab required us to measure the resistance of 5 different very small, very simple resistors with 5 bands. The colors were Yellow, Purple, Black, Black, Brown. The values received looked like this. Also The the color band of each resistor and their tolerances as well as a picture of the materials used in the first part. The second part involved: a voltage divider with 4 new resistors each having only 4 bands( with 2 different color schemes), a digital multimeter, and a signal generator. Which is shown below as well as the tables. The second part of this Involved us measuring the Voltage instead of the Resistance like part A The 3rd part consisted of using a 5Mhz sweep/Function generator, and an oscilloscope. We had to guess the Period, frequency, and amplitude based on the small tiny boxes representing 5 mili-seconds. We then repeated this step with a different wave function. Shown as Trial 2. The uncertainty equation is shown Directly below ​ or Using this ​ Part 1 Below https://preview.redd.it/56089n0khri41.png?width=947&format=png&auto=webp&s=4cea85a87e12e7c3e6ffd9a3bd6b37eb804eca9c The second part involved: a voltage divider with 4 new resistors each having only 4 bands( with 2 different color schemes, a digital multimeter, and a signal generator.
