1. I am given a curve defined parametrically by [tex] x= 2/t , y=1-2t [/tex] i have found the equation of tangent at t=-2 to be y=4x+9, they have asked whether it cuts the curve again. how do i find that, since i don't know the original equation of the curve and can't solve them simultaneously.
2. Also they have asked to find an approximation for sec 61. I have used [tex] \frac{\delta y}{\delta x}= \frac{dy}{dx} [/tex], but i did not get the answer, 2.0605. How do i get about doing it?
