Sir in first question how do we know that at x= x0 function gives negative value? If it would give positive value then there would be no root??

[@krishnadeshmukh2928]

If it would give positive value it would have never intersected the y axis,,but as point 0,-1 lies we can surely say it does intersect xaxis.

[@devanshgupta3473]

Sir in question 1 why we can’t use descarte rules of sign and why only we use rolles theorem please sir this is my major doubt?

[@krishnadeshmukh2928]

Descartes rule is used to check the maximum possible positive and negative roots.There is no specificity for the number of real roots.

[@aadi6116]

Sir in the third question if we observe the first inequality we can find derivative of fx is >0 answer will be only 0,1

[@tulsibhayal3254]

Sir in last question fof (x) = 0 you have taken x1,x2,x3 but it is root of f(x).There for fof (x)we have input 0 in fof (x) and at that point it's value will be 1. There for the answer is wrong

Please help at 34:40 Difficulty in getting . Only one kaise sir

[@gtimeducation]

challenge Success Let me reply in sometime

[@tushargoyaliit]

Yes sir jab b aap free hue .... Ab sir probability pe ache questions ki video please .

[@gtimeducation]

There may be other methods to solve this like a = (sin 2x + 9)/(sin(x + pi/4)) and studying the function for its range for the period 2pi. We may find that the range of the function is (-infinity, -10) U (10, infinity). Then we can say that line y = a will cut the graph only if a E (-inf., -10) U (10, inf.). Now in our method we have used substitution. We have t = sin x + cos x. The range of the sin x + cos x is [-sqrt(2), sqrt(2)]. So, when we draw the graph we will consider t on x-axis from -sqrt(2) to sqrt(2) only. In that case we want have full parabola, but part of the parabola. Also, t E [-sqrt(2), sqrt(2)], graph will cut x-axis in this interval for which we must have f(-sqrt(2))f(sqrt(2)) < 0. Also both roots cannot be in this interval as product of roots is 8. This contradiction is occurring as we substituting unbounded function for bounded function, but if we keep in mind this limitation, we wont consider full graph. So, exactly one root will lie in interval [-sqrt(2), sqrt(2)]. Infact here there is not point of discussing second root as graph is not full parabola, but the part of the parabola.

Sir by god mai bahut teachers se pada hu But aapke jaisa teacher (guru) i challenge koi nahi hai Na kota me na Chandigarh Really thankful to u

Sir next should be probability plz

[@offtheday1802]

In all question how had you assume that that bottommost point of graph is on f(0)

[@gtimeducation]

Ankit Malik It is by chance graph has been drawn like that otherwise f(0) is not bottommost point.

[@SandeepKumar-yv9xd]

Thanks sir

[@ninadkimmatkar2272]

Sir may you please elaborate on the third question, is (c,0) being considered as the vertex and why are alpha and beta on opposite sides, as there is no condition that suggests that?Also, we could say if the concavity is downwards, alpha and beta will be on the same side

[@happysingh6586]

Yes bro i am also thinking this, both alpha and beta can be negative and grater than -2 , and similarly they can be positive also, i thik sir has left some cases

[@Abitube47]

(C,0) is not vertex. (0,C) is vertex. Hence the roots will be 0 +_ z. Where z needs to be less than 2 according to question
