WebA A is the hypotenuse of the right triangle. A_x = A \cos\theta Ax = Acosθ A_y = A \sin\theta Ay = Asinθ Figure 1a: We analyze a vector by breaking it down into its perpendicular components, A_x Ax and A_y Ay. [Does cosine always align with the x-axis and sine with the y-axis?] Determining the magnitude of the resultant WebIn addition, the calculation formulas of sine entropy and partial sine entropy of uncertain random variables are given. Entropy is usually used to measure the uncertainty of uncertain random variables. It has been defined by logarithmic entropy with chance theory. However, this logarithmic entropy sometimes fails to measure the uncertainty of ...

WebJan 6, 2016 · Explanation: This can be expanded through the tangent angle addition formula: tan(α +β) = tanα + tanβ 1 −tanαtanβ. Thus, tan(x + y) = tanx + tany 1 −tanxtany. The tangent addition formula can be found using the sine and cosine angle addition formulas. sin(α +β) = sinαcosβ +cosαsinβ. cos(α + β) = cosαcosβ− sinαsinβ. Since ...
