It depends entirely on the shape that you are trying to find the surface area of. For a cube, simply add up the areas of each side: http://study.com/academy/lesson/how-to-find-the-surface-area-of-a-cube.html For a cylinder there is a different formula altogether: http://study.com...
c^2 {/eq}. The variables a and b are lengths of the sides, also known as catheti (plural form of cathetus), of the triangle that are adjacent to the right angle. The variable c is the length of thehypotenuse, which is the side of aright trianglethat is opposite to its right ...
Using ideas of conversion from polar to rectangular form and vector addition, waves of the same frequency can be easily combined. 7. Unit vectors have length 1. To find the unit vector in the same direction as a vector r divide the vector by its length: rˆ = r|r|. 8. Any ...
If the equation of base of an equilateral triangle is2x−y=1and the vertex is(−1,2),then the length of the sides of the triangle is (a)√203(b)2√15(c)√815(d)√152 View Solution A vertex of an equilateral triangle is(2,3)and the opposite side isx+y=2.Find the equatio...
and the parameternow has the meaning of theDebye length, which is the typical length scale of the interactions. The limitis called the quasineutral limit. The mean-field limitof the system (1.6) formally leads to the Vlasov–Poisson equation, as discussed above. Several authors [3,4,8,9,...
A weak form of (1) based on a generalized Nitsche’s method is considered, hereby embedding all types of boundaries. The weak formulation is to find \(u_h \in \mathcal {V}^P_h\) such that \(\forall v_h \in \mathcal {V}^P_h\), where ...
A line drawn from the center to any point on the circle has the same length; that length is called the circle's radius. An arc is a part of the circle between any two points on the outside of the circle. In the image below, point A is the center of the circle. The line ...
This situation corresponds to a hole that is collapsed to a single point, and line integrals of finite quantities for such a path (of zero length) will vanish. In turn, we conclude that (7.56)∫∂V(∇×B)·nˆdA=0, where B and the volume V are arbitrary. Note that ∂V is...
The radius of the circle (length = 1 unit) represents the hypotenuse of the right triangle. So, the sides of the right triangle are 1, x, y.By the definition of the trigonometric ratios, we havesinθ=OppositeSideHypotenuse=y1 ⇒y=sinθ...
Period of a Cosine Function Trigonometric functions calculate the values of ratios of sides in a right triangle. In particular, the cosine function {eq}\cos \theta {/eq} is the ratio of the side adjacent with the angle {eq}\theta {/eq} to the hypotenuse: $$\cos \theta = \dfrac{A}...
