Wikipedia may supplement a textbook by explaining key concepts, but it does not replace a textbook. Wikipedia is organized as hypertext, meaning that the information you require may not be on one page, but spread over many pages. In technical subjects, the material may also be technical: Wikipedia has no restriction on the depth of coverage.
A frequently studied problem in finite geometry is to identify ways in which an object can be covered by other simpler objects such as points, lines, and planes. In projective geometry, a specific instance of this problem that has numerous applications is determining whether, and how, a projective space can be covered by pairwise disjoint subspaces which have the same dimension; such a ...
Subject lines contribute to both mood and linear perspective, giving the viewer the illusion of depth. Oblique lines convey a sense of movement, and angular lines generally convey dynamism and possibly tension. Lines can also direct attention towards the main subject of the picture or contribute to the organization by dividing it into compartments.
Peanut butter being spread on white bread . This is a list of spreads. A spread is a food that is literally spread, generally with a knife, onto food items such as bread or crackers. Spreads are added to food to enhance the flavour or texture of the food, which may be considered bland without it.
Divine Proportions defines both of these concepts directly from the Cartesian coordinates of points that determine a line segment or a pair of crossing lines. Defined in this way, they are rational functions of those coordinates, and can be calculated directly without the need to take the square roots or inverse trigonometric functions required ...
A student will usually have different exercise books for each separate lesson or subject. The exercise book format is different for some subjects: for the majority of subjects, the exercise book will contain lined paper with a margin , but for other subjects such as mathematics , the exercise book will contain squared paper to aid in the ...
Some students studying math may develop an apprehension or fear about their performance in the subject. This is known as math anxiety or math phobia, and is considered the most prominent of the disorders impacting academic performance.
A frequent method for displaying formulas on their own line has been to indent the line with one or more colons (:). Although this produces the intended visual appearance, it produces invalid html (see Wikipedia:Manual of Style/Accessibility § Indentation). Instead, formulas may be placed on their own line using < math display = block >.
