Complete Explanation of CBSE Notes
Physics is the study of matter, basic principles and laws of nature along with their manifestations. The study of physics is mainly involved in the explanations of the diverse phenomena of its concepts. Please refer Physical World Class 11 Notes for more revision notes.
Students generally face a lot of pressure when they have to appear for exams. Besides, when exams are just around the corner, completing the final revision can prove to be of tremendous help to students. While revision is not just about reading notes, it should be a holistic process where students cover all the necessary concepts that will further help them to prepare well and attempt all the questions in the examinations with ease.
While preparing any concept, it is generally observed that the students don’t make proper revision notes. As a result, while revising any particular chapter they tend to miss out several crucial tips and formulas that are important from an examination point of view. Please refer Class 11 Physics notes for more revision notes.
Random experiments; outcomes, sample spaces (set representation). Events; occurrence of events, ‘not’, ‘and’ & ‘or’ events, exhaustive events, mutually exclusive events, Axiomatic (set theoretic) probability, connections with the theories of earlier classes. Probability of an event, probability of ‘not’, ‘and’ and ‘or’ events. Please refer Probability Class 11 Notes for more revision notes.
Measures of dispersion; Range, mean deviation, variance and standard deviation of ungrouped/grouped data. Analysis of frequency distributions with equal means but different variances. Please refer Statistics Class 11 Notes for more revision notes.
Mathematically acceptable statements. Connecting words/ phrases – consolidating the understanding of “if and only if (necessary and sufficient) condition”, “implies”, “and/or”, “implied by”, “and”, “or”, “there exists” and their use through variety of examples related to real life and Mathematics. Please refer Mathematical Reasoning Class 11 Notes for more revision notes.
Derivative introduced as rate of change both as that of distance function and geometrically.Intutive idea of limit. Limits of polynomials and rational functions, trignometric, exponential and logarithmic functions. Definition of derivative, relate it to slope of tangent of the curve, derivative of sum, difference, product and quotient of functions. Please refer Limits and Derivatives Class 11 Notes for more revision notes.
Coordinate axes and coordinate planes in three dimensions. Coordinates of a point. Distance between two points and section formula. Please refer Introduction to Three Dimensional Geometry Class 11 Notes for more revision notes.
Sections of a cone: circles, ellipse, parabola, hyperbola; a point, a straight line and a pair of intersecting lines as a degenerated case of a conic section. Standard equations and simple properties of parabola, ellipse and hyperbola. Standard equation of a circle. Please refer Conic Sections Class 11 Notes for more revision notes.
Let us consider a fixed vertical line (l) and let (m) be another line intersecting line (l) at any fixed point V. Let α be the angle of intersection between line l and m. If line m is rotated around line l such that the angle of intersection (α) remains constant. Then, the resultant surface is a double-napped circular hollow cone. Where V is known as the vertex, l is the axis and m is known as the generator of the resultant cone.
The vertex separating the cone into 2 different parts is known as the nappes. The section obtained by the intersection of a cone with the plane is known a the conic section. Based on the angle and position of the intersecting plane w.r.t. cone, different types of conic sections can be obtained. Please refer Conic Sections Class 11 Notes for more revision notes.
Brief recall of two dimensional geometry from earlier classes. Shifting of origin. Slope of a line and angle between two lines. Various forms of equations of a line: parallel to axis, point-slope form, slope-intercept form, two-point form, intercept form and normal form. Please refer Straight Lines Class 11 Notes for more revision notes.
