To find where a tangent meets the curve again, first find the equation of the tangent. Then use simultaneous equations to solve both the equation of the tangent and the equation of the curve.

The formula given below can be used to find the equation of a tangent line to a curve. (y - y1) = m (x - x1) Here m is the slope of the tangent line and (x1, y1) is the point on the curve at where …

May 9, 2025 · Learn how to find tangent lines using derivatives in calculus. Understand the concept, formulas, and 4 main techniques with step-by-step examples.

Therefore the tangent line to a given line at any point will always match the original equation of the line. That just means that linear functions make for boring tangent line questions!

This structured practice takes you through three examples of finding the equation of the line tangent to a curve at a specific point.

This calculus video tutorial explains how to find the equation of the tangent line with derivatives.

The slope can be found using the derivative of the function, and the point of tangency can be found by substituting the x-coordinate of the point into the original function.

The slope of a tangent line is same as the instantaneous slope (or derivative) of the graph at that point. We can find the equation of the tangent line by using point slope formula y y 0 = m (x x …

Mar 10, 2025 · To find the equation for the tangent, you'll need to know how to take the derivative of the original equation. Sketch the function and tangent line (recommended). A graph makes …

To find the equation of the tangent line to a function at a given point, first find the slope of the tangent line using the derivative. Then, use the point-slope form of the equation of a line: y y 1 …
