When a figure is plotted on a coordinate plane, the coordinates of the pre-image can be multiplied by the same number to find the coordinates of the image. If the coordinates are multiplied by a number greater than 0 but less than 1, the image will be smaller than the pre-image, as ...

If P (x, y) is a point that must be rotated 180 degrees about the origin, the coordinates of this point after the rotation will only be of the opposite signs of the original coordinates. Below is how the formula for the 180-degree rotation of a given point is represented. Before Rot...

What is Rotation Matrix?A rotation matrix can be defined as a transformation matrix that operates on a vector and produces a rotated vector such that the coordinate axes always remain fixed. These matrices rotate a vector in the counterclockwise direction by an angle θ. A rotation matrix is ...

that any imperfections in the strut, through faulty workmanship or material or eccentricity of loading, can be allowed for by giving the strut aninitial curvature. For ease of calculation this is assumed to be a cosine curve, although the actual shape assumed has very little effect on the ...
The trigonometric function is a class of functions in mathematics that belong to transcendental functions in elementary functions. They are essentially mappings between sets of any angle and variables of a set of ratios. The usual trigonometric functions are defined in a plane Cartesian coordinate ...
