Unformatted text preview: θ , is equal to the latitude of the location of the pole. So you can find from the shadow, and given the radius of the earth you can find the distance to the equator. Write this distance as a formula involving the measured distance so that you can use the formula given in class 1 to find the uncertainty in the distance, as well as the value. 1 If we have y = f(x) and σ x is the uncertainty in x , then y (the uncertainty is y ) is given by x y x y ∂ ∂ = . The derivative of y with respect to x is the sensitivity of y to fluctuations in x ....
