Question

Tangent line of a curve?

Answer 1

Have you found the slope of \(l\) yet?

Answer 2

This is also new to me. I have a bad professor.

Answer 3

What do you know so far?

Answer 4

Do you know about derivatives yet?

Answer 5

If not, do you know about the difference quotient?

Answer 6

Well, my interpretation is that the line that is tangent to the graph of y = 2x^2 at the point (1,2), basically it touches the graph of 2x^2 at that point. And the angle at which that tangent line intersects the x-axis is phi. That's what I know.

Answer 7

I don't know that answer though. I'm only in pre-calc.

Answer 8

Derivatives aren't new to me, just this section. I have take calc AB before so I know some claculus

Answer 9

*calculus

Answer 10

But does this section permit that you use derivatives?

Answer 11

Yea.

Answer 12

Find the derivative of y at x = 1

Answer 13

That will be the slope of the tangent line. Do you know how to convert this slope into an angle?
