If a cos theta + b sin theta = c, prove that a sin theta + b cos theta = ± √(a^2+b^2-c^2)

Sir bahoot bhardiya me dusre method se kar rha tha but maine cossquare theta = 1-sinsquare theta lagana bhul gaya tha thanks for this video sir

[@BhupendraSingh-yq2om]

Sir bindass fanduclass fantastic 👌 outstanding

[@vaibhavgamer1343]

Sir pahle wale method Mein dono ka square plus kyon karte hain iska Koi Bhi reason Hai Kya please reply

[@AviJainClasses]

Reason ye hai ki dono mein terms ek hain .... and square karne pe dono mein jab aap 2ab ka answer nikalte hain toh answer same aata hai ... toh 2ab eliminate kar sakte hain .... 2ab eliminate karne ke baad ji bhi ratios bachega, wo square mein hoga and we can apply the formula.... pehla wala method janna isliye jaruri hai kyunki isse is type ke aur 1-2 doosre questions bhi solve ho jate hain .... aap second method se bhi solve kar sakte hain ...

Ausome sir ,and nice way of teaching

[@gayathrivsaji]

Thanks sir, please upload the basic theory of trigonometry

[@manalimourya1042]

Your explanation is superv

[@tanjiroop9712]

1 doubt Why does every question has a unique solution why why like whyy!!!!

[@abhinavpratik4228]

Ty so much brother❤️

[@pranavrajmathsacademy]

sir..second proof is nice.

[@Hello-yf2nf]

Thank you sir , nice explanation

[@learnwithmilky8315]

❤❤❤❤ good explanation

[@arpitsinghsingh800]

Thank you sir

[@trendsgayu]

Sir but square kyu karenge starting mein aur kis basis par karenge

[@AviJainClasses]

Is type ke 4-5 questions hote hain, unko solve karne ka trick hai ye .... is mein galti nahi hoti is method se .... jo given hai wo and jo find karna hai wo ... un dono ke squares se answer mil jata hai ... bas jo given hai aur jo find karna hai un mein ratio same hone chahiye and co efficients new nahi hone chahiye ... jaise is mein a and b hain .... agar ye method hard lag raha hai toh next method se bana sakte hain aap .... dono ekdum sahi hai ...

[@vaibhavithakur5814]

Thank you soo much sir🙏😀

[@ArnavvvSR]

Awesome Sir ❤❤❤

[@AkashSethi-qd4vv]

Very very very nice explanation sir ..... Awesome......

[@scoutingvisionwithpranjay3745]

Sir 2 method acha hai ....nice explanation both methods are good but 2 is perfect

[@pranavrajmathsacademy]

u cannot add LHS of two diff eqn.. first proof is not correct.

[@AviJainClasses]

We aren’t adding l.h.s of two equations here ... because the second equation is yet to be proved .. otherwise we can definitely add the l.h.s of the two equations and they will be equal to the r.h.s of the two ... as as far as this solutions goes , what I have done here is I have found out the value of the squares of the two l.h.s with the given information ... hope you are getting what I am trying to say ... both the solutions are 100% correct ❤️❤️

[@trimbakmunde2337]

Great sir

[@priyanshgarg1292]

tnks sir

[@braredi999]

Very nice

[@adarshraj0507]

Jab bhi root iss side se uss side jata h to +_ kyu ho jata h sath me

[@DEEPAKPathariya-gx1ri]

Sir trigonometry ke basic concepts ki Puri video kareye na pls

[@AviJainClasses]

Okay champion ... I will surely try to make that as soon as I get time ....

[@ajitsingh905]

Thanks 👍🏻

[@JagdeepSingh-wk1wd]

Love it😍😍😍

[@rozarigamer9050]

sir please youtube pe aajoa new new trickke sath please sirr we want you

[@rushikeshingle4694]

tan Alpha is equal to b sin theta divided by a + b cos theta prove this equation
