find double diffentiation of x=a cost ,y= b sint​

Answer 1

Answer:

find double diffentiation of x=a cost ,y= b sint​

Step-by-step explanation:

by using

dy/dx=(dy/dt)/(dx/dt)

dy/dt=bcos(t)

dx/dt=-asin(t)

dy/dx=(-b/a)cot(t)

then d^2y/dx^=

$=\frac{-b}{a} \frac{d(cott}{dt} *\frac{1}{dx/dt} \\=\frac{bcosec^2(t)}{a} *\frac{1}{-asin(t)} \\=\frac{-bcosec^3(t)}{a}$
