WebThe sample variance formula is given as: s 2 = 1 n − 1 ∑ i = 1 n ( x i − x ―) 2 Here, s2 = Sample variance n = Number of observations in sample xi = ith observation in the sample x ― = Sample mean Standard Deviation Formula The population standard deviation formula is given as: σ = 1 N ∑ i = 1 N ( X i − μ) 2 Here, σ = Population standard deviation WebSteps to Calculate the Coefficient of Variation: Step 1: Calculate the mean of the data set. Mean is the average of all the values and can be calculated by taking the sum of all the values and then dividing it by a number of data points. Step 2: Then compute the standard deviation of the data set. That is a little time-consuming process. WebThe first variation of area refers to the computation d d t ω t = − W t, H ( f t) g ω t + d ( ι W t ∥ ω t) in which H(ft) is the mean curvature vector of the immersion ft and Wt denotes the variation vector field ∂ ∂ t f t. Both of these quantities are vector fields along the map ft. cuhk pacc syllabus

WebConsider a variation $f: (-\epsilon,\epsilon)\times [0,a]\rightarrow M$ such that $f (s,0)=p_0$ and $f (s,a)=\phi (s)$. Let $E$ be the energy associated with $f$. By the first variation of energy formula, we have that $$\frac {E' (0)} {2}=\langle v,\gamma' (a)\rangle$$ Now, because $\phi$ is contained in $N$, we can conclude that $E' (0)=0$.
