The divergence test asks whether the nth term of the series has a non-zero limit. If the result is a non-zero value, then the series diverges. Using L’Hopital’s rule, find the limit of the given function.limn→∞ (an) = limn→∞ (n2) / (5n2+4) ...

In the low-frequency range, the optical amplitude is inversely proportional to the square root of the frequency (∆I ∝ f−0.5; diffusion-limited process), while in the high-frequency range, it is inversely proportional to the frequency (∆I ∝ f−1; surface charging process). ...
When a peak in intensity is observed, equation 1 is necessarily satisfied. Consequently, we can calculate d-spacings based on the angles at which these peaks are observed. By calculating the d-spacings of multiple peaks, the crystal class and the crystal structure parameters material sample can ...
My goal is to create a random set of numbers that add up to a particular total. In the image below, you'll see a column of 10 numbers and its total in A12. What function would I need to insert in order to randomize the 10 numbers, but still end up with a total o...
We can think of the Heckman likelihood function as follows: b1 = coefficients on selection equation b2 = coefficients on regression equation max L_samp = Product L_i b1,b2 L_i = L(DOES NOTwork | b1) if A observation = L(DOESwork and y=yhat | b1, b2) if B observation = L(DOES...
Determining the state of magma reservoirs is essential to mitigate volcanic hazards. However, geophysical methods lack the spatial resolution to quantify the volume of eruptible magma present in the system, and the study of the eruptive history of a volc
the equation of state of superdense matter2and the theory of general relativity in the strong field limit3,4,5,6, while their unparalleled emission stability could allow detecting nanohertz gravitational waves7. Millisecond pulsars also enabled the first detection of an extra-solar planetary system8...
