Complete step-by-step answer: Plotting point P (x,y) on a graph paper: When plotting a point P (x,y), we move x units on x-axis and y units on the y-axis. If x is positive, then we move x units in the right direction.

2 days ago · More formally, a graph can be defined as follows: A graph \(G\) consists of a set of \(V\) of vertices (or nodes) and a set \(E\) of edges (or arcs) such that each edge \(e \in E\) is associated with a pair of vertices \(\in V\). A graph \(G\) with vertices \(V\) and edges \(E\) is written as \(G=(V,E)\).

5 days ago · Basis of trigonometry: if two right triangles have equal acute angles, they are similar, so their corresponding side lengths are proportional.. In mathematics, the trigonometric functions (also called circular functions, angle functions or goniometric functions) are real functions which relate an angle of a right-angled triangle to ratios of two side lengths.
