**Find the equation of a tangent line science.answers.com**

29/10/2008 · Find the equation of the line tangent to the graph of f at that point by finding a line that intersects the cure in exactly one point. Do not use the derivative to find this line. Do not use the derivative to find this line.... The tangent line to a curve at a point {eq}(a, b) {/eq} is a line that touches the curve at this point without crossing over it. Its slope therefore is the same as the slope of the curve at the

Find the equation of the tangent line to the curve at the point . The equation of this tangent line can be written in the form where Find the equation of the tangent line to the curve at the point .... Finding the Intercepts. For the x and y intercepts [denoted here as x0 and y0 respectively], simply use the tangent equation. It may be useful to note that the intercepts are (x0,0) and (0,y0) so plugging in zero for the correct variable allows you to find a intercept.

**derivatives how to find tangent line at a given point**

If we know both a point on the line and the slope of the line we can find the equation of the tangent line and write the equation in point-slope form 1 Recall that a line with slope \(m\) that passes through \((x_0,y_0)\) has equation \(y - y_0 = m(x - x_0)\text{,}\) and this is the point-slope form of the equation.. how to fix my feet from hurting The EQUATION OF THE SLOPE OF ANY OF THOSE TANGENT LINES is f (x).So, yes, you are correct that the EQUATION of the slope of the tangent line to ANY point on a cubic (3rd degree polynomial) is a quadratic (2nd degree polynomial).To find a SPECIFIC slope, you …

**find the equation of the tangent line y=x^2 at x=2**

You can solve this problem without calculus if you know that a tangent is at right angles to the radius at the point of contact. Thus the line from the centre of the circle to the point of cantact of the tangent to the circle is perpendicular to the tangent and thus has slope -1. how to join the fornite tournmeant dreamhack Note that in the last problem, we are given a line parallel to the tangent line, so we need to work backwards to find the point of tangency, and then find the equation of the tangent line. Here is one more; in this problem, we’ll find the equation of a parabola that goes through a certain point and is tangent to a line at another point.

## How To Find The Tangent Line Without Knowing The Equation

If we know both a point on the line and the slope of the line we can find the equation of the tangent line and write the equation in point-slope form 1 Recall that a line with slope \(m\) that passes through \((x_0,y_0)\) has equation \(y - y_0 = m(x - x_0)\text{,}\) and this is the point-slope form of the equation..

- To find the line’s equation, you just need to remember that the tangent line to the curve has slope equal to the derivative of the function evaluated at the point of interest: $$\bbox[yellow,5px]{m_\text{tangent line} = f'(x_0)}$$
- Find the Equation of the Tangent Line to the Ellipse. Find the equation of the tangent and normal to the ellipse at the point . We have the standard equation of an ellipse. Now differentiating equation (i) on both sides with respect to , we have. Let be the slope of the tangent at the given point , then. The equation of the tangent at the given point is. This is the equation of the tangent to
- Note that in the last problem, we are given a line parallel to the tangent line, so we need to work backwards to find the point of tangency, and then find the equation of the tangent line. Here is one more; in this problem, we’ll find the equation of a parabola that goes through a certain point and is tangent to a line at another point.
- 31/01/2013 · Talking about tangents to straight lines is also a little weird as well - the tangent to a straight line is the line itself; we normally refer to tangents when talking about actual curves, the tangent is the line that touches the curve and thus has the same instantaneous slope as the curve at that point.
