" 8."x=a sec theta,y=b tan theta

Show that the equation of the normal to the hyperbola x= a sec theta, y=b tan theta at the point ( a sec theta, b tan theta) is, ax cos theta + b y cot theta=a^(2)+b^(2) .

If x =a sec theta, y =b tan theta then (dy)/(dx) =

If x=a sec theta,y=b tan theta, then prove that (x^(2))/(a^(2))-(y^(2))/(b^(2))=1

If x=a sec theta , y=b tan theta find (d^2 y )/( dx^2) at x = (pi )/( 6)

Eliminate theta between the equation : x =a sec theta, y= b tan theta .

If x=a sec theta and y=b tan theta , eliminate theta .

If x = a sec theta, y = b tan theta " then " (dy)/(dx) = ?

If x = a sec theta, y = b tan theta " then " (dy)/(dx) = ?

If x = a sec theta , y =b tan theta , then (d^2y)/(dx^2) at theta = pi/6 is :
