If you ask an engineering aspirant, you come across iitjee maths video lectures trigonometry, especially an IIT JEE one, he will tell you the reality of a triangle. The world sees a triangle as a figure with 3 vertices and 3 lines, but it is more than just 3 lines. It is a big chapter in itself which helps the engineers to figure out and design many things. The branch of mathematics that deals with the sides, lengths, angles and everything else of a triangle is called trigonometry. While most of the students grasp this subject pretty well, some learners find it hard to consume and digest. It is entirely not their fault that they fail to understand the sin and cos, the teacher is to be equally blamed. Anyway, that being said, here are the things that a student must learn to excel in trigonometry. So he is able to solve trigonometric equations.

Trigonometric Ratios

These are the basic and the most important part of trigonometry. It will not be wrong to say that these ratios form the basis of the chapter. We will not get into what these are and how to calculate, but we surely want to tell you that if you want to build a strong base in trigonometry, then understanding and learning these ratios is the first thing you must do.

Trigonometric Equations

The next step towards being a trigonometry guru understands the trigonometric equations. These equations are like the rules of sides and angles of the triangles. They are the laws by which each and every valid triangle is drawn or can be drawn. In case any of this equation fails for a triangle, it cannot even exist.

Height and Distance

This is one part of the trigonometry chapter which is a practical application of the trigonometric identities, ratios and equations. This chapter enables a student to find the length or the distance of a point from any given point. Similarly, there are many other practical applications of trigonometry which are covered in the engineering.

Trigonometry is one of the few chapters that are interesting to read and if you go through IIT JEE maths video lectures for trigonometry, it gets even more interesting. One of the reasons it becomes interesting is the fact. That you can actually see what does identities and ratio. Rather than just reading from the book and wasting hours in an effort to understand.

We have created excellent IIT JEE maths video lectures for trigonometry. That not only focuses on teaching the concepts of trigonometry but also focuses on its practical applications.

These JEE math videos on trigonometry display and explain the procedures and methodology. That involved in solving the questions. It talks about the right approach and how the study of triangles. That can be simplified and picked up quickly and easily.

These videos are one of the few videos from our very special JEE maths training videos. That we have developed for the IIT aspirants. If you are looking for excellent IIT JEE maths video lectures on trigonometry, your search is about to end!

Maths for iit jee physics video lectures

Study of iit jee physics by video lectures is very good idea, that can be very beneficial for jee students.
The main hurdle in study of physics is the weak maths. Almost every chapter physics needs sound knowledge of maths.
Although we study basic maths before we start study of physics but it is not sufficient. To understand why it is not enough,
let us list out topic wise need of maths.

One and two dimensional motion needs algebra like equation solving, logarithms, trigonometry ratios, identities,
coordinate geometry, calculus and vectors.
Gravitation needs binomial theorem and definite integration.
That means only first chapter of physics needs almost all maths of class 11th and 12th.
Newtons laws of motion, SHM and rotational mechanic video lectures needs differential equations.
Wave motion need idea of trigonometric equations additionally.
For optics conic section topics from coordinate geometry is needed.

Optics needs idea of 3d and vectors with all other maths.

Electricity and magnetism are already defame due to use of differential equations.
Modern physics uses exponent and logs to solve problems.

So almost all maths is needed in the study when prepare, for jee mains and, for jee advance by physics video lectures.

Topic to read before physics videos for iit jee are finally.

Quadratic equations, Binomial theorem and exponential and logarithms.
Trigonometric ratios and equations and inverse trigonometry.
Coordinate geometry of 2 and 3 dimensions from point to conic sections.
Entire calculus from function to integrations, differentiation and differential equations.
Vectors sum, dot and cross products. (Sometimes differentiation of vector is also needed.)
For few problems of 1 d motion and alternating currents avg needed.
In thermo dynamics some idea of mean mode and median is also needed.

Off course, Learning that much maths means student has to give full time for maths.
Maths itself is big subject in fact the toughest one.
So what to do for this maths.

Yes, Study at any coaching center will not give that all maths.
Coaching center starts all three subject at the same time.
That only confuses a student between all topics.
Only iit jee maths video lectures can do this for a student.

Because any maths chapter can be learnt any time any where.
Student can do proper start of iit jee preparation.

Finally get the best of iit jee master videos for maths and do it first, then do physics then chemistry.

Functions iit jee maths lectures

Topic of function is very big and topics related to it are limits, continuity and differentiation.
Although this is first topic in calculus for jee maths lectures, but most teacher do not teach it
at first priority. This leads to mess up all the jee maths, as calculus is very important subject.
It is the most useful topic for physics as well. So being week in calculus will be disastrous.

Without video lectures of maths functions it is not possible to understand limits continuity or differentiability.
Most teacher starts calculus with limits because problem solving in limits is easy and student enjoys it.
This way teacher gets confidence of students but student do not get confident in functions yet.
Problems on limits needs idea of functions. But it is managed by teachers some how and time passes away.

But all that practice finally wastes time, and knowledge is still incomplete.
So we recommend to learn maths video lectures of functions before limit and continuity videos.

Preparation of iit jee maths video lectures of functions can be the best way to start the calculus.
Functions is big topic so student need to understand what exactly he has to learn.

Here is the property of function that we learn for maths video lectures for iit jee.

Functions are real.
Functions are single valued.
Functions are of single variable.

Types of function we learn

Inverse trigonometric functions.
Logarithmic function.
Algebraic functions.
Trigonometric functions.
Exponential functions.

Algebraic function have so many types and others are called transcendental functions.
Keeping importance of function we should learn it at first place.
How to find domain and range of functions?
That is the most asked question. And it can be answered only after correct knowledge of functions.
After that student will be able to get all of limits continuity in less time, and whole calculus be matter of a few days.
