Im currently trying to solve a Math Exercise from the book "Morris Kline - Calculus An Intuitive and Physical Approach" and iv been struggling to get a grip on it.
I think i know how to solve it but there is that missing puzzle piece that eludes me. My thought process was Finding the derivative of the slope thus finding out the slope of the line that will intersect the X Axis...but this is where i got stuck. I cant figure out how to use the Ecuation of a Line to prove the Exercise.
Can someone help me please?
HINT... let the $x$ abscissa be $2pt$ where $t$ is a parameter, so the corresponding $y$ value is $pt^2$. Then write down the equation of the tangent at this point.
