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 ...
The vector cross product (2i + 6j + 27k) × (i + pj + qk) = 0 implies that the two vectors are parallel. For the cross product to be zero, the components must satisfy the condition: 2p + 6q ...
The correct answer is (b) John Dalton. John Dalton proposed the first atomic theory in the early 19th century, which stated that matter is made up of indivisible particles called atoms, and that atoms of the same element are identical ...
