Hello I have the question 'Find the equations of the tangents to these curves at correspnding points '
I'm getting very frustrated becuase I cannot where I'm going wrong . Heres how i've been doing it.
y=2/x² , x=2 hence points (2,1/2)
y=2x-² (Is this where I went wrong?)
dy/dx = 4*1/8
Yet this isnt the line equation
