When a complex number z is written in polar form?
Space and AstronomyA complex number z in polar form is given as r(cosθ+isinθ) and is often abbreviated as rcisθ, where r equals the modulus of the complex number. The value θ is called the argument of z, denoted by arg(z). Note that r(cos(θ+2kπ)+isin(θ+2kπ)) represents the same complex number for every integer k. When a complex number is

What is stellar wobble?
Space and AstronomyStellar Wobble. What we measure at the telescope is a change in the wavelength in light coming from a star over the course of days, months, and years. This changing wavelength is the Doppler shift of the light, resulting from the star orbiting a common center of mass with a companion planet. How does the

How do you define parallel and perpendicular lines?
Space and AstronomyParallel lines are lines in a plane that are always the same distance apart. Parallel lines never intersect. Perpendicular lines are lines that intersect at a right (90 degrees) angle. What is parallel lines and perpendicular lines? Parallel lines are always the same distance apart for their entire length. Perpendicular lines cross each other at
