यदि `y=(cotx+cosecx)` तो `(d^(2)y)/(dx^(2))` ज्ञात कीजिए

If t=(x^(4)+cotx), find (d^(2)y)/(dx^(2)) .

If y=cotx show that (d^2y)/(dx^2)+2y(dy)/(dx)=0 .

If y=("cosec "x+cotx) , prove that (sinx)(d^(2)y)/(dx^(2))-y^(2)=0.

int(cotx)/(cosecx-cotx)dx=

If y^2=P(x) , then 2d/dx(y^3(d^2y/dx^2))

If y^2=P(x) , then 2d/dx(y^3(d^2y/dx^2))

If sin(x+y) = cos(x-y), then the value of cos^2 x is: यदि sin(x+y) = cos(x-y), तो cos^2 x का मान ज्ञात करें :

If y=(tanx+cotx)/(tanx-cotx)," then: "(dy)/(dx)=

If 9x^2+y^2=37 and xy = 2 , x, y> 0 , then the value of (27x^3+y^3) is : यदि 9x^2+y^2=37 और xy = 2 , x, y> 0 , तो (27x^3+y^3) का मान ज्ञात कीजिए ।
