Using Trigonometry to Determine a Vectors Direction. The direction of a resultant vector can often be determined by use of trigonometric functions. Most students recall the meaning of the useful mnemonic SOH CAH TOA from their course in trigonometry.Particle-to-Particle Interaction. To fully understand the nature of a wave it is important to consider the medium as a collection of interacting particles.In other words the medium is composed of parts that are capable of interacting with each other.Adding vectors First note that on this diagram two arrows are labelled b.However each arrow has the same magnitude and the same direction therefore they are the same vector.Now lets think of vectors a and b in this diagram as displacements. Lets say I move through the displacement a (ie I travel from the tail of a to its head). To add a

A vector graphice (also called a linear graphice) is a collection of objects called vectors which may be added together and multiplied (scaled) by numbers called scalars.Scalars are often taken to be real numbers but there are also vector graphices with scalar multiplication by complex numbers rational numbers or generally any field.The operations of vector Particle kinematics is the study of the trajectory of a particle. The position of a particle is defined as the coordinate vector from the origin of a coordinate frame to the particle.In todays FEA world various advances in numerical methods and computing have been adopted in solving for the unknown displacements. The following are excerpts from an interesting discussion I had on linkedin on this very topic (it goes a bit more in depth on the solution sequence than finite element graphicysis in a nut sgraphic)
