    Answer:

    first let the points be

    A(4,-1),B(-2,-3)

    first let us take the ratio as 1:2 and later 2:1 since its trisection  .

    let the point joining A and B be P(x,y)

    Step-by-step explanation:

    P = (1*-2+2*4/1+2  ,  1*-3+2*-1/1+2)

      = (-2+8/3  ,  -3-2/3)

      =  (6/3  ,  -5/3)

    P   =  (2  ,  -5/3)

    now let ratio be 2:1

    P = (2*-2+1*4/3  ,  2*-3+1*-1/3)

      = (-4+4/3  ,  -6-1/3)

      = (0/3  ,  -7/3)

    P = (0 , -7/3)

    In verse mein numerator denominator ho jata hai aur

    denominator numerator ban jata hai

    example 

    3/4 ka inverse =4/3

    7=7/1 ka invese=1/7

    1/9 ka invese=9/1=9

    =cosec(90-30)=sec30 ( As cosec(90-θ)=secθ)

    so θ=30

    Now 2cos2θ-1

    Gaurav Seth 5 years ago

    Explanation:

    S.P of Rs. 5000 stock = Rs.(156100*5000)Rs.156100*5000= Rs. 7800. 

     

    Income from this stock = Rs.(12100*5000)Rs.12100*5000 = Rs. 600.  

     

    Let investment in 8 % stock be x and that in 9 % stock = (7800 - x).

     

    Therefore,  

     

    (x*890)+(7800−x)*9108=[600+70]x*890+7800-x*9108=600+70  

     

    4x45+7800−x12=670⇔x=36004x45+7800-x12=670⇔x=3600 

     

    Therefore,  Money invested in 8 % stock at 90 = Rs. 3600.

     

    Money invested in 9 % at 108 = Rs. (7800-3600) = Rs. 4200.

    Let us use a  trick to solve it quickly

    99x + 101y = 499 ............ i

    101x + 99y = 501............ ii

    subtract i  from  ii

    2x - 2y = 2
    x - y =1
    x = 1 + y   ........   iii

    add i and  ii

    200x + 200y = 1000
    x + y = 5 .................................. iv

    Now from iii and  iv  ,  we get  1 + y + y = 5       or          2y = 4       or        y = 2     ......  v

    again from iii and  v   , we get  x = 1 + 2 = 3

    Hence x = 3  ,  y = 2

    5x + 2y = -3 ........ (i)
    x + 5y = 4
    x = 4 - 5y ........... (ii)
    Put (ii) in (i), we get
    5(4 - 5y) + 2y = -3
    20 - 15y + 2y =-3
    - 13y = - 3 - 20
    -13y = -23
    y = 23/13
    Put value of  y in (ii), we get
    x = 4 - 5(23/13)
    x = (52 - 5)/13 = 47/3

    5m - 3n = 19 ......... (i)
    m - 6n = -7 ........... (ii)
    Multiple (i) by 2 , we get
    10m - 6n = 38........... (iii)
    Subtract (iii) and (ii), we get
    (10m - 6n)- (m - 6n) = 38 - (-7)
    10m - 6n - m + 6n = 38 + 7
    9m = 45
    m = 5
    Put m = 5 in (ii) we get
    5 - 6n = -7
    -6n = -7 - 5
    -6n = -12
    n = 2

    ____________
    13x=65
    x = 65/13=  5
