In three-dimensional geometry the yz-plane consists of all points where the x-coordinate is zero. Its equation is given by x = 0. Any point on this plane is represented as (0 y z). The yz-plane is perpendicular to the x-axis ...
In three-dimensional geometry the equations of the x-axis are given by y = 0 and z = 0 since all points on the x-axis have y and z coordinates equal to zero. In parametric form the x-axis is represented as ...
In Class 12 Maths Three Dimensional Geometry the reflection of a point across a plane is found by using the perpendicular distance formula. The image of a point is equidistant from the plane but on the opposite side. This concept ...
Cosines represent the ratio of the adjacent side to the hypotenuse in a right triangle. They help define wave oscillations, circular motion, and Fourier analysis. The cosine function is periodic, with a range from -1 to 1, and plays a ...
