Homework Statement


Find the parametric form for the tangent line to the graph of y=2x2−5x+3 at x=2 is

Homework Equations


I have no clue!


The Attempt at a Solution


I found the tangent line to be y=3x-5

I know that the answer has to be in the form...

<x0,y0>+t<x1-x0,y1-y0>

I have absolutely no idea what is x0,y0,x1, or y1.

So I am just really confused on how to put it in the requested form.

There are a lot of choices for x0, y0, x1 and y1. Pick any two points on your tangent line. Put x=2 and get y=1. So (2,1) is a choice for (x0,y0). Pick x=3. What do you get for y? That's a choice for (x1,y1). There's no one form for a parametric line. Pick any two points you want.
 
Thank you Dick. That actually makes a lot of sense! I was just making the problem too hard (as usual).
 
Prove $$\int\limits_0^{\sqrt2/4}\frac{1}{\sqrt{x-x^2}}\arcsin\sqrt{\frac{(x-1)\left(x-1+x\sqrt{9-16x}\right)}{1-2x}} \, \mathrm dx = \frac{\pi^2}{8}.$$ Let $$I = \int\limits_0^{\sqrt 2 / 4}\frac{1}{\sqrt{x-x^2}}\arcsin\sqrt{\frac{(x-1)\left(x-1+x\sqrt{9-16x}\right)}{1-2x}} \, \mathrm dx. \tag{1}$$ The representation integral of ##\arcsin## is $$\arcsin u = \int\limits_{0}^{1} \frac{\mathrm dt}{\sqrt{1-t^2}}, \qquad 0 \leqslant u \leqslant 1.$$ Plugging identity above into ##(1)## with ##u...
