Prove that Cos6x=2cos²3x-1 |
|
Answer» Cos6x=cos2(3x)(Cos2x=2cos²x-1)Similarly cos2(3x)=2cos²3x-1 hence prove abee oyee adarsh gali hame bhi aati h lekin itne mental nahi ki kahin pr bhi bak de Bhai iss Adarsh mein to bilkul bhi ADARSH nahi h iss khate h irony in english Adarsh jwale apni gand m aag lagale Kutte kamine kyu ghussa dila Diya. Trigonometry dekhate hi mujhe bhayankar gussa Aata Hai. Man toh kar Raha Hai Tera murdur kardu. Bhosdi Ka saala Yaha trigonometry nahi aati aur gaandu sawaal puch raaha Hai Saala |
