What is the range of inverse cosine?
Space and Astronomy[0,π][0,π] . What is the range of inverse sine? [−π2,π2] The graph of y=sin−1x is drawn as follows. The domain of sin−1 is [−1,1] and its range is [−π2,π2]. Why is the range for cosine inverse restricted? With that in mind, in order to have an inverse function for trigonometry, we restrict the domain of
What is the formula for partitioning a segment?
Space and AstronomyLesson Summary Partitioning a line segment, AB, into a ratio a/b involves dividing the line segment into a + b equal parts and finding a point that is a equal parts from A and b equal parts from B. When finding a point, P, to partition a line segment, AB, into the ratio a/b, we
How can you tell if a shape is 2d or 3d?
Space and AstronomyA two-dimensional (2D) shape has only two measurements, such as length and height. A square, triangle, and circle are all examples of a 2D shape. However, a three-dimensional (3D) shape has three measurements, such as length, width, and height. How do you know if a shape is 3D? An object is 3D if it is
What are the four identities?
Space and AstronomyThe four basic algebraic identities are as follows. (a + b)2 = a2 + 2ab + b2 (a – b)2 = a2 – 2ab + b2 (a + b)(a – b) = a2 – b2 (x + a)(x + b) = x2 + x(a + b) + ab. What are the four identities for Class
How do you find the solar azimuth angle?
Space and AstronomyThe solar azimuth angle is the angular distance between the zero azimuth (either due South or due North, depending on what you select on the input screen) and the projection of the line of sight to the sun on the ground. The azimuth angle is measured clockwise from the zero azimuth. How do you calculate
What is a point in a circle?
Space and AstronomyA circle is a set of all points in a plane that are all an equal distance from a single point, the center. The distance from a circle’s center to a point on the circle is called the radius of the circle. A radius is a line segment with one endpoint at the center of
How do you write a linear inequality in two variables?
Space and AstronomyThe solution of a linear inequality in two variables like Ax + By > C is an ordered pair (x, y) that produces a true statement when the values of x and y are substituted into the inequality. The graph of an inequality in two variables is the set of points that represents all solutions
How many angles are there in geometry?
Space and AstronomyRight Angle – An angle that is exactly 90 degrees. Obtuse Angle – An angle more than 90 degrees and less than 180 degrees. Straight Angle – An angle that is exactly 180 degrees.…Summary. Angle Type Angle measure Straight angle 180° Reflex angle Greater than 180°, less than 360° What are types of angles in
Are mutually exclusive events dependent?
Space and AstronomyIf events are mutually exclusive then the events are dependent. Tossing a coin, head or tail is mutually exclusive. But tossing a coin twice, the first time tossing a coin doesn’t affect the second time tossing the same coin which’s independent. Is mutually exclusive independent or dependent? An example of a mutually exclusive event is
