Question: posting together because i already posted one of them on...

Question details
Posting together because I already posted one of them on accident without an explanation. Both of these want to find the error propagation, using the rules attached.
b.Em+ mgh where g is an exact constant but m, v and h are measured values with uncertainties. C. U Vo cos θ where both vo and θ are measured values
Review of Measurement Uncertainty Calculations Here are the rules for propagating uncertainties through a calculation: Addition: z-x + y δΖ 6x + δy This works for any number of terms. Subtraction : z :-x-y-, δΖ 6x + δy This also works for any number of terms. Multiplication by an exact value: z-kx-, δΖ k6x General multiplication/division: z-xy or z --öz Iz( + ) (This works for any number of factors) Exact power: z x δΖ Izlikl sine function : z : sin x-, δΖ-lcosx16x 8x lxl 8x Natural log: z Inx 6z lal
