    3:46 If somebody is having problem in understanding this long solution then you can do this solution by using only 1 triangle as it is very simple and not complicated.
    Sin B=AB/BQ
    Sin Q=AQ/BQ
    As sin B=sin Q
    AB/BQ=AQ/BQ
    BQ gets cancelled
    AB=AQ(Isosceles Triangle)
    Angle B=Angle Q(Angles opposite to equal sides are equal).
    42:36 Ma'am instead of doing this, we can do this:
    tan+sec-1/(tan-sec+1)
    tan+sec-1/(tan-sec)(sec²-tan²)
    As 1=sec²-tan²

    Hello mam . I have seen all the uploaded chapters of mathematics from your channel only. You are literally one of the best teachers I have ever seen in my life. You clear each and every concept of students with your incredible teaching skills. Whatever you teach, is always crystal clear, with no doubts. Furthermore, I request you to please upload the video of chapter ARTHEMETIC PROGRESSION as it is a bit vast. Love from Kashmir 🤍

    Mam .... Ek baat puchni thi .... Example 11 jo krwaya h aapne .... Vo bhi easy h .... Smajh aa gya mujhe .... But mene dekha .... Jo ncert mein solve kra hua h vo example .... Vo or bhi jayada easy h and time kam lega .... Book wale ke hisaab se 1 ya 2 min lagenge....and aapke wale mein 2 ya 3 .... Toh bas ye puchna tha ki exam mein dono mein se kisi bhi tareeke se kre .... Toh number same hi milenge ? Kyuki phir time save ho skta h !.... Just wanted to know ..... Baaki toh aap ho hi problem simplifier 💕🌙
