What are the 3 trig identities?
Space and AstronomySine, cosine and tangent are the primary trigonometry functions whereas cotangent, secant and cosecant are the other three functions.…The reciprocal trigonometric identities are: Sin θ = 1/Csc θ or Csc θ = 1/Sin θ Cos θ = 1/Sec θ or Sec θ = 1/Cos θ Tan θ = 1/Cot θ or Cot θ = 1/Tan
What is the photosphere composed of?
Space and AstronomyWhat is the photosphere layer? Photosphere – The photosphere is the deepest layer of the Sun that we can observe directly. It reaches from the surface visible at the center of the solar disk to about 250 miles (400 km) above that. What are three features of the photosphere? These features include the dark sunspots,
How do you get a Euler path?
Space and AstronomyA directed graph has an Eulerian trail if and only if at most one vertex has (out-degree) − (in-degree) = 1, at most one vertex has (in-degree) − (out-degree) = 1, every other vertex has equal in-degree and out-degree, and all of its vertices with nonzero degree belong to a single connected component of the
What does well defined mean in math?
Space and AstronomyIn mathematics, a well-defined expression or unambiguous expression is an expression whose definition assigns it a unique interpretation or value. Otherwise, the expression is said to be not well defined, ill defined or ambiguous. What do well-defined mean? clearly stated or described Definition of well-defined 1 : having clearly distinguishable limits, boundaries, or features a
What is the constant slope?
Space and AstronomyFor example, a small slope means a small velocity; a negative slope means a negative velocity; a constant slope (straight line) means a constant velocity; a changing slope (curved line) means a changing velocity. How do you find a constant slope? The slope equals the rise divided by the run: . You can determine the
What is the lifespan of a star?
Space and AstronomyStars live different lengths of time, depending on how big they are. A star like our sun lives for about 10 billion years, while a star which weighs 20 times as much lives only 10 million years, about a thousandth as long. Stars begin their lives as dense clouds of gas and dust. What is
What is a linear pair Theorem?
Space and AstronomyLinear pair theorem: If two angles form a linear pair, then they are. supplementary. What is the linear pair theorem example? Video quote: So a linear pair of angles are supplementary to each other they add up to be 180 degrees. An example of where you might see this we've got line again divided by
What is a hidden figures message?
Space and AstronomyWhile “Hidden Figures” introduces many important themes regarding racial injustice and gender inequality, it is apparent that Melfi’s goal was to tell a heartwarming story rather than a historically accurate one. What is the most important message in Hidden Figures? Hidden Figures is an impactful movie in a time of social awareness. It is an
What is a circle in geometry?
Space and AstronomyA circle is a round shaped figure that has no corners or edges. In geometry, a circle can be defined as a closed, two-dimensional curved shape. How do you define a circle in geometry? A circle is the set of all points in the plane that are a fixed distance (the radius) from a fixed
Which way do I turn my caliper piston?
Space and AstronomyWhich way do you turn to loosen a brake caliper? Looking at the upper surface of the bolt-head from above, turning the bolt counter clockwise (CCW) loosens it, clockwise (CW) tightens it. How do you twist a brake piston? Video quote: So you have to put pressure on the piston. And rotate it at the
