Oct 1, 2024 · Solution: The slope of a tangent line can be found by finding the derivative of the curve f (x and finding the value of the derivative at the point where the tangent line and the curve meet. This gives us the slope. For example: Find the slope of the tangent line to the curve f (x) = x² at the point (1, 2).

In this section, we are going to see how to find the slope of a tangent line at a point. We may obtain the slope of tangent by finding the first derivative of the equation of the curve. If y = f(x) is the equation of the curve, then f'(x) will be its slope. So, slope of the tangent is m = f'(x) or dy/dx

- Technically, a tangent line is one that touches a curve at a point without crossing over it. Essentially, its slope matches the slope of the curve...
- I was confused by this as well. I was thinking, incorrectly, that "g'(-1) = -2" means that the tangent line must go through (-1, -2), as you said....
- He chose to use y=mx+b because a tangent line, or the derivative of a function will always be a straight line, and that equation (y=mx+b) is how we...
- A lot of times it won't be so easy to tell where the y intercept is. Basically when the y intercept is not exactly on a marked number.
- That seems to be the point-slope form. It's used to get the equation when a point and the slope are given. This is actually derived from the slope...
- Yes it is. The tangent line is the straight green line he drew, which infact crosses the y-axis at y=1
- Your setup in the second version is correct, but 2-(-2)=4, and 0-(-6)=6, so the slope is still 4/6=2/3.
- Plugging in your point (1, 1) tells us that a+b+c=1. You also say it touches the point (3, 3), which tells us 9a+3b+c=3. Subtract the first from th...
Slope of the tangent at P. The slope of a curve y = f(x) at the point P means the slope of the tangent at the point P. We need to find this slope to solve many applications since it tells us the rate of change at a particular instant. [We write y = f(x) on the curve since y is a function of x.
Nov 16, 2022 · The tangent line and the graph of the function must touch at \(x\) = 1 so the point \(\left( {1,f\left( 1 \right)} \right) = \left( {1,13} \right)\) must be on the line. Now we reach the problem. This is all that we know about the tangent line. In order to find the tangent line we need either a second point or the slope of the tangent line.

The concept of linear approximation just follows from the equation of the tangent line. i.e., The equation of the tangent line of a function y = f(x) at a point (x 0, y 0) can be used to approximate the value of the function at any point that is very close to (x 0, y 0).
