Question

Can someone please tell me how you find the slope of the tangent line

Answer 1

given a curve, you can find the derivative of the curve. At any given point, the derivative evaluated at that point is the slope of the tangent line.

Answer 2

-how do you find the derivative of the curve?

Answer 3

do you have a specific curve in mind?

Answer 4

y=x^2 at the point (2,4)

Answer 5

y=x^2 through the point (7,49) use this tangent line to estimate squareroot of 50

Answer 6

\[ \frac{dy}{dx} = 2x \]
\( \frac{dy}{dx} \) represents the change in y over the change in x

Answer 7

what is the 2x?

Answer 8

ohhh the derivative of x^2
