      =2
      400sec
      2
      x⋅csc
      2
      x

      Simplifying the Product:
      Recall that:
      sec

      2
      𝑥
      =
      1
      cos

      2
      𝑥
      sec
      2
      x=
      cos
      2
      x
      1

      csc

      2
      𝑥
      =
      1
      sin

      2
      𝑥
      csc
      2
      x=
      sin
      2
      x
      1

      Therefore:
      sec

      2
      𝑥

      csc

      2
      𝑥
      =
      1
      cos

      2
      𝑥

      1
      sin

      2
      𝑥
      =
      1
      sin

      2
      𝑥
      cos

      2
      𝑥
      =
      1
      (
      sin

      𝑥
      cos

      𝑥
      )
      2
      sec
      2
      x⋅csc
      2
      x=
      cos
      2
      x
      1


      sin
      2
      x
      1

      =
      sin
      2
      xcos
      2
      x
      1

      =
      (sinxcosx)
      2
      1

      Using the Double-Angle Identity:
      sin

      2
      𝑥
      =
      2
      sin

      𝑥
      cos

      𝑥
      sin2x=2sinxcosx
      So:
      (
      sin

      𝑥
      cos

      𝑥
      )
      2
      =
      (
      sin

      2
      𝑥
      2
      )
      2
      =
      sin

      2
      2
      𝑥
      4
      (sinxcosx)
      2
      =(
      2
      sin2x

      )
      2
      =
      4
      sin
      2
      2x

      Therefore:
      sec

      2
      𝑥

      csc

      2
      𝑥
      =
      1
      (
      sin

      2
      𝑥
      2
      )
      2
      =
      4
      sin

      2
      2
      𝑥
      sec
      2
      x⋅csc
      2
      x=
      (
      2
      sin2x

      )
      2
      1

      =
      sin
      2
      2x
      4

      Simplifying Further:
      25
      sec

      2
      𝑥
      +
      16
      csc

      2
      𝑥

      2
      400

      4
      sin

      2
      2
      𝑥
      25sec
      2
      x+16csc
      2
      x≥2
      400⋅
      sin
      2
      2x
      4


      =
      2

      40

      sin

      2
      𝑥

      =2⋅
      ∣sin2x∣
      40

      =
      80

      sin

      2
      𝑥

      =
      ∣sin2x∣
      80

      Issue with Direct AM-GM Application:
      The lower bound provided by the AM-GM inequality is not tight:
      80

      sin

      2
      𝑥

      ∣sin2x∣
      80

      This expression does not provide a specific minimum value because it varies with
      𝑥
      x. The AM-GM inequality gives us a lower bound, but it doesn't help us find the exact minimum value in this case.
      Conversion to Tangent and Cotangent
      Using Trigonometric Identities:

      tan

      The reason the direct AM-GM approach does not yield the correct minimum value for

      𝑥

      2
      x+16csc

      x is due to the nature of the trigonometric functions involved. The transformation to
      tan

      𝑥
      tanx and
      cot

      𝑥
      cotx simplifies the expression to a form where the minimum value can be accurately found using standard calculus techniques.

      @@adityayadav78417 Yup bro you can. As you are seeing it for the first time, in the beginning, you might not get the concepts in the first go that time just repeats that portion. Don't go for 1.5x, watch it at normal speed. You might be getting confused too, pause the video and think for a few mins by yourself. If not getting still then watch that part again!!!. After completing the replay, do all the class questions again by yourself.

    1:03:38 we can answer the question easily by the basic of formula of a right angled triangle that 1/2(bh)= Area
    so as per question: 48=bh
    by trial and error we can get 6,8:
    by pythagoras theorem hypotenuse in 10
    hence 6,8,10 are in AP smallest no. is 6.

    @hridaysheth_ Год назад +4

    sir at 1:47:15 the other method you took turned out to work, but was mathematically incorrect. This was an infinite gp and the value of number of terms wasnt given so we cannot assume that there are 10 terms in the gp thus also value of A1 and A7 wouldnt be equal. Taking your method, suppose we took 11 terms, then A3 wouldnt be equal to A5 and similarly other terms. If it was given in the question that there were 10 terms in the increasing Gp, then your method is correct but this method by luck worked in your favour. In such a situation, what else could we possibly do other than the usual kaatapeeti😅

    Bhai jo 2:05:25 pe question diya hai aapne AGP ka, usme mene basic definition of AGP lagaya, toh mujhe 'd' me ek Quadratic aaya and jab mene un values se 'r' nikala toh mujhe r ki 2 values aai, r= 3/4 and r= 1/2. Aapne jo answer key diya hai usme sirf 1/2 consider kiya hai. So is 3/4 valid or not?
