## Homework Statement

Calculate the following, expressing all results with uncertainties both in absolute and relative (percentage) form:

a) A + B

b) A x B

c) Asin(theta)

d) A^2 / Bcos(theta)

The relevant formula for the absolute uncertainty is below, but i have no idea how to use it! The teacher just sort of gave us the assignment without much explanation.. I know that it uses something called partial derivatives, could someone explain how to find that?
