- यदि y = x sin x, साबित करें कि (1)/(y).(dy)/(dx) - (1)/(x) = cot x
Text Solution
|
- अगर y = (x - a) (x-b), , तब x का मान जिसके लिए (dy)/(dx) = 0 is
Text Solution
|
- यदि y = (cos x + sin x)/(cos x - sin x), तो (dy)/(dx) =
Text Solution
|
- यदि y = x sin x, तो ((dy)/(dx))^(2) + y^(2) =
Text Solution
|
- यदि f(x) = 1 + x + (x^(2))/(2)+ (x^(3))/(3) +…+(x^(50))/(50) तो f'(1)
Text Solution

- यदि y = (x)/(x+5), तो x.(dy)/(dx) + y^(2) =
Text Solution
|
- यदि f(x) = (2x^(2) - 4)/(3x^(2) + 5), तो f'(0) =??
Text Solution
|
- यदि f(x) = (x)/(1+tan x), तो f' (0) =
Text Solution

- lim(h rarr 0) (f(a+h) - f(a))/(h) =
Text Solution
|
- यदि f(x) = (1- cosx)/(1+cosx), तो f'((pi)/(2)) =
Text Solution
|
