Which way is diagonal line?
Space and AstronomyIn geometry, a diagonal line is a straight line segment that joins two corners of a polygon, but is not an edge. It goes through the middle of the shape. It does not go straight up, down, or across. Is diagonal side to side or up and down? Explain that the children can move vertically

What is the derivative of inverse sine?
Space and AstronomyThe derivative of the sine inverse function is written as (sin–1x)’ = 1/√(1-x2), that is, the derivative of sin inverse x is 1/√(1-x2). What is the derivative of the inverse of? Video quote: So the derivative of the inverse function is also equal to 1 over the derivative of the function with respect to Y

Do exterior angles add up to 180?
Space and AstronomyRemember the interior and exterior angle add up to 180°. Do all exterior angles add up to 180? An exterior angle of a triangle is equal to the sum of the two opposite interior angles. The sum of exterior angle and interior angle is equal to 180 degrees. Can an exterior angle be 180 degrees?

Does 1 mean true or false?
Space and Astronomytruetrue—in fact any nonzero integer) are used. Does true mean 1? Each of the operators yields 1 if the specified relation is true and 0 if it is false. The result has type int. For any pair of operands, exactly one of the relations is true. The && operator shall yield 1 if both of

What is Minkowski distance in data mining?
Space and AstronomyMinkowski distance calculates the distance between two real-valued vectors. It is a generalization of the Euclidean and Manhattan distance measures and adds a parameter, called the “order” or “p“, that allows different distance measures to be calculated. What is Minkowski distance? Minkowski distance is a distance measured between two points in N-dimensional space. It is

What type of function is absolute value?
Space and AstronomyAn absolute value function is a function that contains an algebraic expression within absolute value symbols. Recall that the absolute value of a number is its distance from 0 on the number line. Is absolute value a linear function? The function inside the absolute value is NOT linear, therefore the graph contains curves. Is absolute

How do you write a product as a power?
Space and AstronomyWhat does it mean to write the product as a power? The product of powers rule tells us that when you are multiplying two terms that have the same base, you can just add their exponents to find your answer. How do you write a product as a power of one? Video quote: So that's

Does the sun shine everyday?
Space and AstronomyANSWER: The truth is that the sun is always shining and will shine continuously until it dies. The question to answer here is “Why do we not see the sun at night, and why do we only see it during the day?” Technically, we say “day” to mean when we can see the sun shining,

What is the formula for mutually exclusive events?
Space and AstronomyIf A and B are said to be mutually exclusive events then the probability of an event A occurring or the probability of event B occurring that is P (a ∪ b) formula is given by P(A) + P(B), i.e., P (A Or B) = P(A) + P(B) What is the formula for mutually inclusive

How do they clean in space?
Space and AstronomyThe astronauts do some cleaning between their duties. They use liquid detergent, disposable plastic gloves, multi-purpose wiping cloths and a vacuum cleaner for cleaning. To clean, they spray the detergent, wipe with the cloth, and vacuum the dust. How do astronauts get rid of poop in space? In the absence of gravity, space toilets use
