- Once the tangent is found you can use it to find the gradient of the graph by using the following formula: (text {Gradient to the curve =}~frac {y_2-y_1} {x_2-x_1}) where (({x_1,~y_1})) and (({x_2,~y_2})) are any two points on the tangent to the curve.

Learn how to construct and use tangents to find gradients of curves. Use this information to find areas, accelerations and velocities.
To determine the equation of a tangent to a curve: Find the derivative using the rules of differentiation. Substitute the \ (x\)-coordinate of the given point into the derivative to calculate the gradient of the tangent.
Jun 30, 2023 · To find an estimate for the gradient: Draw a tangent to the curve. Find the gradient of the tangent using Gradient = RISE ÷ RUN. It is an estimate because the tangent has been drawn by eye and is not exact. (To find the exact gradient we would need to us e differentiation)

Nov 16, 2022 · The gradient vector \(\nabla f\left( {{x_0},{y_0}} \right)\) is orthogonal (or perpendicular) to the level curve \(f\left( {x,y} \right) = k\) at the point \(\left( {{x_0},{y_0}} \right)\). Likewise, the gradient vector \(\nabla f\left( {{x_0},{y_0},{z_0}} \right)\) is orthogonal to the level surface \(f\left( {x,y,z} \right) = k\) at the point ...
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. A function \(z=f(x,y)\) has two partial derivatives: \(∂z/∂x\) and \(∂z/∂y\).
