  1. Hace 5 días · Derivatives can be used to obtain vectors tangent to and perpendicular to given curves and surfaces. Specifically: The gradient operator – ∇ = (∂/∂ x , ∂/∂ y) in 2D, or ∇ = (∂/∂ x , ∂/∂ y, ∂/∂ z) in 3D – can be used to obtain vectors perpendicular to curves and surfaces represented with implicit algebraic equations.

  2. Hace 4 días · Polar curves are defined by points that are a variable distance from the origin (the pole) depending on the angle measured off the positive x x -axis. Polar curves can describe familiar Cartesian shapes such as ellipses as well as some unfamiliar shapes such as cardioids and lemniscates. r=1-\cos {\theta}\sin {3\theta} r = 1 −cosθsin3θ.

  6. Hace 2 días · The goal of this lab exercise is to study the phenomena of magnetic hysteresis and calculate the retentivity, coercivity and saturation magnetization of a material using a hysteresis loop tracer (HLT-111). The remote trigger equipment allows you to control the applied magnetic field (H).

  7. Hace 5 días · Hitchcock made famous brief appearances in his own movies, as a sort of signature. "Vertigo" is a rare case where the director's unmistakable physiognomy is never seen. Answer: False. Hitchcock appears as a man walking past a boatyard. 15. The score for "Vertigo" was made by one of the most celebrated composers that ever worked with movies.
