Figure 5.3.1: By the Mean Value Theorem, the continuous function f(x) takes on its average value at c at least once over a closed interval. Exercise 5.3.1. Find the average value of the function f(x) = x 2 over the interval [0, 6] and find c such that f(c) equals the average value of the function over [0, 6]. Hint. Evaluate sin(10°)sin(30°)sin(50°)sin(70°), no calculators but use the co-function identity and double angle identity. Subscribe for more math for fun videos How to find Sin Cos Tan Values? To remember the trigonometric values given in the above table, follow the below steps: First divide the numbers 0,1,2,3, and 4 by 4 and then take the positive roots of all those numbers. Hence, we get the values for sine ratios,i.e., 0, ½, 1/√2, √3/2, and 1 for angles 0°, 30°, 45°, 60° and 90°. Tìm Giá Trị Chính Xác sin(50 độ ) Step 1. Kết quả có thể được hiển thị ở nhiều dạng. Dạng chính xác: Dạng thập phân: . Oto nieco pośredni sposób uzyskania wariancji: Pozwolić $X_k$ być liczbą na $k$bilet, $k=1,2,\ldots,m$. Mamy więc jednolity rozkład dla $X_k$mianowicie $$ P(X_k=j)=\begin{cases}\frac{1}{n}&,\text{ if }j=1,2,\cdots,n\\\\\,0&,\text{ otherwise }\end{cases}$$ Więc, \ begin {align} \ operatorname {Var} (X_k) & = E (X_k ^ 2) - (E (X_k)) ^ 2 \\\\ & = \ frac {n ^ 2-1} {12} = \ sigma ^ 2 \ ,, \ text {powiedz} \ end {align} Jeśli korelacja między $X_i$ i $X_j$ $\,(i\ne j)$ być $\rho$, następnie $$\rho=\dfrac{\text{Cov}(X_i,X_j)}{\sigma^2}$$ Szukasz \ begin {align} \ operatorname {Var} (X) & = \ operatorname {Var} \ left (\ sum_ {k = 1} ^ m X_k \ right) \\ & = \ sum_ {k = 1 } ^ m \ nazwa operatora {Var} (X_k) +2 \ sum_ {i
