- Tangent Line to a Level Curve
The tangent line to a curve at a given point is the line which intersects the curve at the point and has the same instantaneous slope as the curve at the point. Finding the tangent line to a point on a curved graph is challenging and requires the use of calculus; specifically, we will use the derivative to find the slope of the curve.
To find the tangent to a curve from an external point, first find the point ‘a’ on the curve where the tangent is. To do this, differentiate the function and set this equal to the change in y over the change in x from the external point to point ‘a’ on the curve.
The tangent line to a curve at a given point is a straight line that just "touches" the curve at that point. So if the function is f(x) and if the tangent "touches" its curve at x=c, then the tangent will pass through the point (c,f(c)).
Aug 17, 2024 · Use the gradient to find the tangent to a level curve of a given function. Calculate directional derivatives and gradients in three dimensions.
Nov 20, 2023 · Using the derivative to find a tangent. At any point on a curve, the tangent is the line that goes through the point and has the same gradient as the curve at that point. For the curve y = f (x), you can find the equation of the tangent at the point (a, f (a)) using.
Enter the equation of a curve and coordinates of the point at which you want to find the tangent line. The tangent line calculator finds the equation of the tangent line to a given curve at a given point.
