To define xxx and yyy as functions of a parameter ttt.
dy/dx=(dy/dt)/(dx/dt)dy/dx = (dy/dt) / (dx/dt)dy/dx=(dy/dt)/(dx/dt) using the chain rule.
d2ydx2=ddt(dydx)dxdt\frac{d^2y}{dx^2} = \frac{\frac{d}{dt}(\frac{dy}{dx})}{\frac{dx}{dt}}dx2d2y=dtdxdtd(dxdy).
Differentiate x=f(t)x = f(t)x=f(t) and y=g(t)y = g(t)y=g(t) with respect to ttt.
Use y−y1=m(x−x1)y - y_1 = m(x - x_1)y−y1=m(x−x1) with m=dy/dtdx/dtm = \frac{dy/dt}{dx/dt}m=dx/dtdy/dt.
Differentiate xxx and yyy, then divide dydydy by dxdxdx.
The point is (2,2)(\sqrt{2}, \sqrt{2})(2,2) when θ=π/4\theta = \pi/4θ=π/4 on the curve.
Solve t−1=3(1/(t+1))t - 1 = 3(1/(t+1))t−1=3(1/(t+1)).
y=2(x+1)−1y = 2(x + 1) - 1y=2(x+1)−1, normal point (−1,−1)(-1, -1)(−1,−1).
The Cartesian equation is y=1x−2y = \frac{1}{x} - 2y=x1−2.
