MAM IS a singer.
Entertainer.
Teacher.
Finally an all-rounder

[manishbaroliya]

Best method is compound angles
S+S = 2SC
S-S= 2CS
C+C = 2CC
C-C = -2SS
(S= SIN, C = COS ) 🤩☺️
I hope you understand...🤔

In Q. 3 the formula actually is = sin2^nA/2^nSinA

mam,
57:38
Q no. 07
2sinx [2cosx^2 - 2cosx + 1] = 3
the above equation in cosx has D<0
=> it has no solutions
correct option is "D=no solution"

[anusmitasamanta]

Super duper techniques to remember these formulas 😁😁

1:09:32 MAM WHAT DID YOU SAY !!🤣🤣🤣🤣🤣🤣🤣

Question 2 (32:10) can be done more easily by the *a^3+b^3=(a+b)(A^2-ab+b^2)* and the *cos(3a)=4cos^3(a)-cos(a)* formulae, straight up algebra and just one conversion of cos 150 to (- sin 60), and done :)

Last Question: •cos³xsinx + sin³xcosx
•cosxsinx(1)
•1/2√2
Thank you mam but this way it would have been easier.

[harshitupadhyay]

In the 10th ques., calculation can be made easy by after
Cos2x(1-4sin²xcos²x)
=Cos2x(1-(2sinxcosx)²)
=Cos2x(1-sin²2x)
=Cos2x.cos²2x
=Cos³2x
=Cos³(2.π/8)
=Cos³(π/4)
=(1/√2)³
=1/2√2

World's best teacher possess infinite perfection in ur profession mam

[uniqueraid]

Lecture begins at 4:13 😎
Thanks me later

[namaprasanna]

For 10 th question I have another method which is very simple
Take 3π\8 as π/2-π/8
Then take sinπ/8.cosπ/8 common use sub multiple formula
This process is very simple and quick 🙂

[anusha]

Mam is an angel 😇
Thankyou so much mam for all the efforts you're putting in for us..
Mission Trigonometry and Mathematical reasoning accomplished 🌈
Next 🎯:-Mission sets

[mdshujaullah]

Ma'am aapne last question ko itna long bnaya ha mainne isko 2 line main bnaya (2 cosAcosB wala formula or 2sinAsinB) wala lgaaie

[aswanikumar]

The best teacher I've ever seen ☺😀😀

[collegemasti-]

Mam ham last vale question mein 3π/8 ko π/2-π/8 karke solve kar sakte hai.

[Raja-qfwi]

Neha mam please talk in English because some tamil students also watching this video please mam

[radhikashenoypai]

THANK YOU MA‘AM YOU ARE THE BEST !!!😄😏😊
I ALWAYS HAD A PROBLEM WITH TRIGONOMETRY
BUT NOW THANKS TO YOU, ALL MY DOUBTS HAVE BEEN CLEARED !!!
