Trigonometry

Hello friends,

I am writing this post for all the students who want to learn trigonometry, especially for CBSE Boards students. It has been a rumour that Trigonometry is very difficult. One has to remember so many formulas and trigonometric value to solve the questions. This is totally a myth.

The fact is that this branch of mathematics is the easiest branch of mathematics. The difficulty which is faced by the students is in Ex. 8.4 of Ch-8 Class-X where the students have to prove the identities with the basic trigonometric identities.Since Boards are very near, I have prepared the Video lectures for the entire Ex. 8.4 which will help all the students.

Before that, I have also prepared some lecture on basic Trigonometry which will work as the revision for all the students.

Lecture 1: Basic Trigonometric Ratios in terms of Perpendicular, Base & Hypotenuse...


Lecture 2: Trick to remember the complete trigonometric value table



Lecture 3: Basic Trigonometric Identities & some solved numerical questions based on the identities




After the Revision, Lets jump to the final Exercise of Chapter 8 i.e. Ex. 8.4

Question wise Video lectures:

Ex 8.1 Ques 1



Ex 8.1 Ques 2



Ex 8.1 Ques 3




Ex 8.1 Ques 5 part 1




Ex 8.1 Ques 5 part 2


Ex 8.1 Ques 5 part 3



Ex 8.1 Ques 5 part 4




Ex 8.1 Ques 5 part 5




Ex 8.1 Ques 5 part 6



Ex 8.1 Ques 5 part 7



Ex 8.1 Ques 5 part 8



Ex 8.1 Ques 5 part 9



Ex 8.1 Ques 5 part 10


I hope these lectures will help you & you all score very good marks in your Boards Exam

Best of luck for your exams.

Coordinate Geometry: Section Formula

Image
Hi Friends, This is the third part of the Coordinate Geometry series. The first part contains Distance Formula. The second part contains finding Area of triangle through coordinates of vertices of the triangle. .In this part, we are going to discuss about the section formula used to find the intersection point on a line which is divided in a given ratio. In the given Figure, the line joining the points (x1, y1) & (x2, y2) is divided by the point (x,y) in the ratio m:n. The coordinates of the point can be calculated by the section formula Video tutorial contain the solved examples, how it can be applied in various questions.

Coordinate Geometry: Distance Formula

Image
Hey friends, Today I am here to discuss something about Distance formula which is used to calculate the distance between two points or coordinates on the co-ordinate plane. Co-ordinate geometry is the study   where the position of point  is described using an ordered pair of numbers.   Such ordered pair looks something like (x, y), where x is the distance on x-axis of the coordinate plane & y is the distance on y-axis of the coordinate plane. where, x1: x coordinate of first point x2: x coordinate of second point y1: y coordinate of first point y2: y coordinate of second point D: Perpendicular distance between the two points. Watch the video for solved numericals based on Distance formula. I hope you will like it.
