Proof of sin3x, cos3x, tan3x formula | trigonometry class 11 | by epselon

Hello Guys, Welcome to our channel Epselon
In this video i have explained best method to derive the identities of sin3x, cos3x and tan3x so that student can understand this trigonometric formula easily.
Trigonometry is one of the most important topics in mathematics. There are so many identities in Trigonometry and it is very confusing to remember these identities.
Prove : Sin 3x = 3 Sinx - 4 Sin ³x | Sin 3x & Cos 3x | Prove : Cos 3x= 4 Cos³x -3 Cosx | Triple Angle Formula |
Trigonometry Class 11 Chapter 3 prove cos3x=4Cos^3x-3 cos x

Sir please tell me ki sin3x = 2sin3x/*2cos3x/2 ho sakta hai ki nahi ??

[@Epselon]

Haan shi hai
