You have killed the difficulties of trigonometry....you are really great sir....India is proud to have teachers like you....A very big salute to you from me sir
Alakh sir should once teach us on this PW Fiundation platform.....what do you say guys???.....the teachers are very good but Alakh sir ke wohi purane vdos h jisme wo oarate huye dikhte ha....abhi sir ek chapter physics ka ap karaiye
I'm in heavy depression with Trigonometric identities. I see all teachers easily prove the questions , but how, I don't know, all I see that they convert one to the other, but why? How should I match that with the final element which is to be proved, Also, While proving It seems to be very puzzled Will I be able to match LHS with RHS after? With some guide, I can properly do that, But unfortunately, The guide will not be there with me in exam 😭
Are u going to appear for 2023 boards? I too have the same problem with trihonometric identities. U have commented four months ago so how is studies goin now? Did you master trigonometry? Are u able to solve these type of questions now?
@@sayannfinity uh i think i have to practice more . Our school just completed the syllabus now and we hav preboards after 5 days soo i'm unable to practice all the subjects 😶 especially maths where i'm stuck. What about ur school ?
@@sayannfinity bhai koi nhi mera bhi yahi hal tha ok But now I am practising more that some my father also told me some tricks And now I can solve 75 percent of RD sharma exercise trigonometry 😃 And that's enough for 92+ Percentage
thank you sir for these wonderful and fantabulous sessions on trigonometry, me being an ioqjs aspirant in class 9 am very helpful to you for your great work
Thankyou so much sir!! You are the best.. literally you explained very well and cleared our doubt and the difficulties we face in this chapter... You are really great sir... maachaa Diya sir humne with the help of you 🔥🔥🔥 thanks a lot!!!❤️🙏🏻
When u have difficulty in any chapter just watch there videos all confusions and difficulties will finished and u can easily score above 90%. Thanku sir 🙏
Sir sach mai maza aagyi jab aap ek ek identity prove kr rhe the kyuki ye mujhe samajh aati thi......thanks a lot ...you made my day🙏🏻✌🏻☺️☺️☺️☺️☺️☺️☺️☺️
tbh at the beginning of the video I wasn't able to solve anything and by the middle of the video i was ale to do until last before steps then now finally here I am able to do all the steps.... Thanks for this huge help
before this video lecture i believe that-TRIGNOMENTRIC IDENTITIES ARE TO MUCH HARD but now i can solve PROOF questions THANK YOU SIR 🤩🤩 FOR A LOVELY EXPERENSE OF TRIGNOMENTRIC IDENTITIS
Doubt : at 40:52 . Sir , how can we divide only one side's numenetar and denominator by cos theta , we have to divide the other side by cos theta as well.
See numerator and denominator mein kisi same quantity se divide ya multiple karne se kuch farak nhi padta hai koi dusri side ko 2/3= 4/6 hai Toh hum RHS mein uper niche 5 se multiple kar de agar Uper niche multiple ya divide karne se result 1 hi aata hai Toh 5/15 which is also same as 4/6
Literally thank you so much sir. Huge respect for the way you teach. I had much like very much difficulty with this chapter and I continued to skip it till now when my pre Boards are the day after tomorrow. I was on the verge of crying but you're a lifesaver sir thank you so much. I have understood the concepts with Crystal clarity. ✨
@@MyChannel-k9c that would be terrifying, like the "upstream and downstream" type of conceptual questions are not in the new edition but what if they gave those type of questions as competency based questions.
Sir I have a trick to solve proof wale questions Our main aim is always to show LHS = RHS SO WE CAN MULTIPLY BOTH LHS AND RHS WITH 0(ZERO) AND THEN LHS AND RHS BOTH WILL BECOME 0 SO, LHS = RHS HENCE PROVED...🤩😏😏
Sir, Class 10 ka trigonometry identities me only sin2q+cos2q hi iss baar ke syllabuses me hai aur vo dono formula nhi hai to aap sir ek video only iss formula pr bana dijiye term l ke bs question aayenge🙏🙏

Although it is not allowed to equate things with zero, I tried doing the same in my UTs, barely passed.
