LEt consider a point in parametric form on this curve (a^2 cos^4 theta, b^2 sin^4 theta) Now write eqn of tangent to this point and then put x=0 and y=0, so you get x and y intercepts and now put...
By using Exclusive & Inclusive formula , which states that if A & B are any 2 sets then cardiality of AUB = card (A) + card (B ) – card (A inter B) card(AUBUC) = card(A)+card(B)+card(C)-card(A inter...
Under root x/x+x+x+…………… here add one and subtract one It becomes under root (x-x+x+………/x+x+x+…………) +1. As x tends to infinity the part under the bracket becomes one and we will be left with under...
It is 1^infi form hence the method to be applied is Lim x-->0 {1^ cosec^2x + 2^cosec^2 x + ….......... n^ cosec^2 x}^ sin^2 x hence e^Lim x-->0 {1^ cosec^2x + 2^cosec^2 x +...
x =a cosϴ and y = b sinϴ.................(1) hence x’ = -asinϴ and y’ = b cosϴ x” = -a cosϴ y” = -bsinϴ d^2y/dx^2 = y”/x” = a/b tan ϴ from eqn 1, tanϴ = bx /ay...
x--> 0 means 1/x^2 → infi e^-infi = 0 Thanks
