  1. high of triangle same-side around the circle is 3 r, to 2r ( 2 ray of circle )

    2 ray of circle to diagonal of square inside the circle is 2 to 2 / sqrt(2)

  2. based on ricle r = 1, course is side of square around of circle, and diagonal from eaual of area of circle, this three values are course of next circle rays

    and 2 r / sqrt ( 2 ) = sqrt ( 2 ) for r = 1

  3. is it a dependence between d ( diagonal of square from equal of area of circle ) to r ( ray of this circle ) d / r

    pi * r ^ 2, pi * sqrt(2) ^ 2, d = sqrt(2) * d ( for third value ) ....

  4. y = (x - 2)^2 / b , for maximum of function y = (x - 2 )^2 + b , for maximum y = 0 , when x = 2

     

     

    y

    y = ( x - 3 ) ^ 2 + b

    b < ( x - 3 ) ^ 2

  5. and what more (b) cant be more ( for x^2 + b ) next values

    for example :

    y = x^2 + b, x = 1, x = 2, maximum is only 1 point

    and the

    b < x^2 + b

  6. and this part x ^ 2 also doeasnt matter, bacause the x ^ 2 after set the x = 0 will be 0, so in this function only matter + 1, to find the top of function. and b value must be > 0 , or < 0, its clear


    i am trying to find the maximum and minimum of this function. and what else use this equal y = b / x has sense ?


    and in equal y = (x-3)^2 + 2, line provide by minimum of this function is y = 3 / 2 x . with equal (x-6)^2 + 1 the line provide by minimum of this function is y = 1/6 x


  7. if we have function like this y = ( x - 2 ) ^ 2 + 1, what we will get if we do : y = - ( ( x - 2) ^ 2 + 1 ) , and more to find the top of function ( highest value ) doesnt matter the ( x - 2) ^ 2 ..... for x-2

    beacause theres allways is 0 to find the top of function

     

  8. about the highest and lowest of function, if we get the lowest value of function like sinus and cosinus ( exmaple ) , od minus them we get the medium of function, but the doing it on back, we maybe get the lowest and hightest of this function

    and if we get y = 2x + 1, and change it to 2x - 1, we can do 2x + 1 / 2x - 1, and dont know if it will make something

  9. so i remember, logarith is dependence between a to c in a^b = c

    so if we have 5 ^ 3 = 125 between 125 and 5 is dependence 125 / 5 = 25, so squart from 2 = 25
