How do you make a Boolean array in Python?
Space and AstronomyA boolean array can be created manually by using dtype=bool when creating the array. Values other than 0 , None , False or empty strings are considered True. Alternatively, numpy automatically creates a boolean array when comparisons are made between arrays and scalars or between arrays of the same shape. What is a boolean array

What are the 4 different types of angles?
Space and AstronomyAngles: Acute, Obtuse, Straight and Right There are four types of angles depending on their size in degrees. What are the 5 types of angles? In geometry, there are various types of angles, based on measurement. The names of basic angles are Acute angle, Obtuse angle, Right angle, Straight angle, reflex angle and full rotation.

What happens when you add two functions?
Space and AstronomyAdding two functions is like plotting one function and taking the graph of that function as the new x-axis. Points of the second function are then plotted with respect to the new axis. For example, (2, 3) becomes “over 2,” “up 3 from the new axis,” or (3, f + 2). Can you add two

How do you find the slanted part of a triangle?
Space and AstronomyTo find the length of the diagonal (or hypotenuse) of a right triangle, substitute the lengths of the two perpendicular sides into the formula a2 + b2 = c2, where a and b are the lengths of the perpendicular sides and c is the length of the hypotenuse. How do you find the slanted side

Why is Earth called spaceship?
Space and AstronomyHe coined the phrase “Spaceship Earth” to describe our planet. He felt that all human beings were passengers on Spaceship Earth, and, like the crew of a large ship, people had to work together in order to keep the planet functioning properly. Can Earth be called a spaceship? Earth can be called “spaceship” because it

What does Prime notation mean?
Space and AstronomyIn calculus, prime notation (also called Lagrange notation) is a type of notation for derivatives. The “prime” is a single tick mark (a “prime”) placed after the function symbol, f. For example: The function f′(x) is read “f-prime of x.” Higher order derivatives are represented by adding more primes. What is a prime notation? One

How far is 3 million miles from Earth?
Space and AstronomySo one way to think of 3 million miles is 120 and a half circumnavigations of the Earth as the crow flies. At an average of 238,857 miles away, you’d have to travel to the moon and back more than six times to cover the distance. How far away is 1 million miles from Earth?

What is differentiability and continuity?
Space and AstronomyWhat is the difference between continuity and differentiability? The difference between the continuous and differentiable function is that the continuous function is a function, in which the curve obtained is a single unbroken curve. It means that the curve is not discontinuous. Whereas, the function is said to be differentiable if the function has a
