What is the slope of a vertical line on a graph?
Space and AstronomyVertical lines have an undefined slope because the horizontal change is 0 — you cannot divide a number by 0. What is the slope of a vertical line? Vertical lines are said to have “undefined slope,” as their slope appears to be some infinitely large, undefined value. How do you find the slope of a

Is parsec a unit of Time?
Space and AstronomyUnfortunately, like the similarly misused ‘light-year’, the parsec is a unit of length, not of time. A parsec is equal to about 3.26 light-years or roughly 31 trillion kilometres (19 trillion miles). The unit has its origins in one of the first methods of determining the distance to the stars. Is unit of parsec is

What is the formula of universal set?
Space and AstronomyA universal set (usually denoted by U) is a set which has elements of all the related sets, without any repetition of elements. Say if A and B are two sets, such as A = {1,2,3} and B = {1,a,b,c}, then the universal set associated with these two sets is given by U = {1,2,3,a,b,c}.

What is Boolean masking?
Space and AstronomyBoolean masking is typically the most efficient way to quantify a sub-collection in a collection. Masking in python and data science is when you want manipulated data in a collection based on some criteria. The criteria you use is typically of a true or false nature, hence the boolean part. How do you make a

How many identities are there in algebraic expressions?
Space and AstronomyThere are four basic algebraic identities in maths. What are the 4 algebraic identities? The standard algebraic identities are: (x + a)(x + b) = x2 + (a + b) x + ab. (a + b + c)2 = a2 + b2 + c2 + 2ab + 2bc + 2ca. (a + b)3 = a3
