Hello,

I am attaching some of the advices by the people who have cracked the exam.

First and foremost, you must strengthen your math fundamentals. You may use YouTube to aid you with this. You may look for topic-specific mathematical lectures . Then, once you've mastered the fundamentals of math,

Hi Aspirant,

It is a chapter dealt in class 7-8.It accentuates the relation between angles of a triangle in terms of cosines,sines and tangents.You may also study about the inverse trigonemetric functions like cot,sec and cosec etc.Its a vety interesting chapter and it is required in almost every field of

Hey there,

Formulas of Tan3x  are:-

Tan3x=(3Tanx-Tan³x)/(1-3Tan²x)

Formula of Tan2x are:-

Tan2x=2tanx/(1-tan²x)

Hope it helps!

Hey there,

(Sinx*Cosx )dx

Using the (u.v)dx formula,

->Sinx*(-Sinx)+Cosx*Cosx

-> -sin²x+cos²x

->cos²x-sin²x

->Cos2x        ( since,cos²x-sin²x)
Hope this helps!

Hello candidate,

First of all, we can replace B as π/2- 2A, or A as π/4- B/2. So, now upon commutating the value of tan(A+B), we get the result as tanA + tan (π/2-2A)/ 1- tanA* tan(90- 2A).

Upon solving the equation, 2 TanA+ tanB, we get the same value

You should have a strong understanding of the basics that is class 10 Trigonometry and must have all the important formulae memorized to solve any problem in Trigonometry.

Also any topic in Maths needs a lots of practice to have a good command on it. So you should focus on
