How do you solve Cotangent?
Space and AstronomyThe cotangent of x is defined to be the cosine of x divided by the sine of x: cot x = cos x sin x . The secant of x is 1 divided by the cosine of x: sec x = 1 cos x , and the cosecant of x is defined to be 1

What is responsible for making stars shine protons the sun the moon photons?
Space and AstronomyThe simple answer is that deep inside the core of the Sun, enough protons can collide into each other with enough speed that they stick together to form a helium nucleus and generate a tremendous amount of energy at the same time. This process is called nuclear fusion. Do photons make stars shine? Over time,

What is the complement in Venn diagrams?
Space and AstronomyThe complement of a set A is everything that is not in A; it is represented by the magenta region in the Venn diagram below (hence the set A is represented by the white region). The union of A and B is everything which is in either A or B, as represented by the magenta

Do planets closer to the sun have a shorter year?
Space and AstronomyPlanets that orbit closer to the Sun than Earth have shorter years than Earth. Planets that orbit farther from the Sun than Earth have longer years than Earth. This happens for two main reasons. If a planet is close to the Sun, the distance it orbits around the Sun is fairly short. Why do planets

Who invented the drawing compass?
Space and AstronomyThe geometric and military compass of Galileo belonged to this class of instruments. Invented in Padua in 1597, the instrument is also linked to Galileo’s activity (fig. 7) in the Accademia Delia (fig. 8), founded in Padua to provide mathematical instruction for young noblemen training for a military career. What is a drawing compass called?
