The tangent is at the point (1, 3). Here, x=1. Substituting x=1 into the gradient function , the gradient at this point is found. and so, m=5. Step 3. Substitute the given coordinates (x,y) along with ‘m’ into ‘y=mx+c’ and then solve to find ‘c’. Since the tangent is at the point (1, 3), this is where x = 1 and y = 3.
Dec 13, 2023 · This is a generalization of the process we went through in the example. The formula is as follows: y = f (a) + f' (a) (x-a) Here a is the x-coordinate of the point you are calculating the tangent line for. So in our example, f (a) = f (1) = 2. f' (a) = -1. Therefore the general formula gives:

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). We can understand this from the example below. Example of Tangent Line Approximation. Use the tangent line approximation to find the approximate value of ∛8.1. Solution

Jun 21, 2023 · The function and this tangent line are shown in Figure 5.2. Figure 5.2: The graph of the function \(y=\) \(f(x)=x^{3}-x\) is shown in black, together with its tangent line at the point \(x=1.5\). The point at which the TL intersects the \(x\)-axis is a (rough) approximation of a nearby zero of the function.
