Why is the sine of 90 degrees 1?
Space & Navigationsin(90) is equal to 1 because you are taking the opposite of the angle over the hypotenuse, and in this situation it just happens to be the same number. Any number over itself equals 1. Is the sine of 90 degrees equal to 1? What is the exact value of sin 90 degrees? The exact
What is the definition of known fact in math?
Space & Navigationknown fact. A fact that you know by memory. expression. A combination of numbers and operations that represent a quantity. What is a known fact in 3rd grade math? Video quote: Using a known fact just simply means that you memorize. The fact. So for a problem like 7 times 5 sometimes things like songs
What is Rotoinversion?
Space & NavigationIn geometry, an improper rotation, also called rotation-reflection, rotoreflection, rotary reflection, or rotoinversion is an isometry in Euclidean space that is a combination of a rotation about an axis and a reflection in a plane perpendicular to that axis. What is Rotoinversion symmetry? The rotoinversion is the symmetry operation required to transpose one object onto
What is a reflection in geometry?
Space & NavigationA reflection is an isometry, which means the original and image are congruent, that can be described as a “flip”. To perform a geometry reflection, a line of reflection is needed; the resulting orientation of the two figures are opposite. How do you describe a reflection in geometry? A reflection is a transformation that acts
What does center center mean?
Space & NavigationCenter and centre have the same meaning. Center is the correct spelling in American English, while in British English centre is correct. Notice that center (and centre) can be a noun, adjective, or a verb. Seeing the two words in real-life examples may help you to visualize how to use them. What does in the
How do you resolve vectors to horizontal and vertical components?
Space & NavigationHow do you resolve vectors into vertical and horizontal components? Video quote: The angle between the slope and the direction of this vector is 55°. We could resolve this vector into two components. One component that is acting perpendicular to the slope or into the slope. How do you find the vertical and horizontal components?
