If `(d^(2)x)/(dy^(2)) ((dy)/(dx))^(3) + (d^(2) y)/(dx^(2)) = k ` , then k is equal to

If (d^(2)x)/(dy^(2))((dy)/(dx))^(3)+(d^(2)y)/(dx^(2))=K then the value of k is equal to

If (d^2x)/(dy^2)((dy)/(dx))^3+(d^2y)/(dx^2)=K then the value of k is equal to

The order of the differential equation [(d^(2)y)/(dx^(2)) + ((dy)/(dx))^(2)]^(-3//2) = k (d^(2)y)/(dx^(2)) is

If x and y are related and also (d^2x)/(dy^2)*((dy)/(dx))^3+k((d^2y)/(dx^2))=0 then value of k is

The degree of the differential equation (d^(2)y)/(dx^(2))+3((dy)/(dx))^(3)=x^(2)log((d^(2)y)/(dx^(2))), is

Write the degree of the differential equation : y.(d^(2)y)/(dx^(2)) + ((dy)/(dx))^(3) = x((d^(3)y)/(dx^(3)))^(2) .

If y=f(x),p=(dy)/(dx) and q=(d^(2)y)/(dx^(2)), then what is (d^(2)x)/(dy^(2)) equal to ?

Find the order and degree of the following D.E's (i) (d^(2)y)/(dx^(2)) + 2((dy)/(dx))^(2) + 5y = 0 (ii) 2(d^(2)y)/(dx^(2)) = (5+(dy)/(dx))^((5)/(3)) (iii) 1+((d^(2)y)/(dx^(2)))^(2) = [2+((dy)/(dx))^(2)]^((3//2)) (iv) [(d^(2)y)/(dx^(2))+((dy)/(dx))^(3)]^((6/(5)) = 6y (v) [((dy)/(dx))^(2) + (d^(2)y)/(dx^(2))]^((7)/(3)) = (d^(3y))/(dx^(3)) (vi) [((dy)/(dx))^((1)/(2)) + ((d^(2)y)/(dx^(2)))^((1)/(2))]^((1)/(4)) = 0 (vii) (d^(2)y)/(dx^(2)) + p^(2)y = 0 (viii) ((d^(3)y)/(dx^(3)))^(2) -3((dy)/(dx))^(2) - e^(x) = 4

If y=e^(2x) , then (d^(2)y)/(dx^(2)).(d^(2)x)/(dy^(2)) is equal to
