+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.Inequality he?
Differentiation lagega
Tan theta find kriye n then theta = tan inv x
BY graph plotting find f(x)>0 kahan kahan pr h
Nhin zrurat h ig
Me kar raha hu
Dekhtehe
Discriminant < 0 for all tanθ>0 is your condition.
Well, that's one condition
You also have the other condition of negative roots.
Pahele quadratic manke solve karo
yeah, for negative roots discriminant can also be greater than or equal to 0
Fir discriminant me jo ayega usko > 0 kardo
Kiyuki tan theta negative nehi ayega
can you pls show the steps
Ha wait
Me thought socha
Waot
okay
Let me tell you how to eliminate two options though. You know that f(θ) →0 as θ→0. Set that condition first, and you get that one of the boundary values of a must be 3
f(theta) > 0 as theta -> 0 is also possible right?
the graph would look something like this
Yes, but the boundary case is it tending to zero
In general it's greater than zero, but one of your bounds is going to be the function tending to zero as input tends to zero
ohh okay
