WebApr 26, 2024 · Explanation: The gradient of the tangent to a curve at any particular point is given by the derivative of the curve at that point. The normal is perpendicular to the tangent so the product of their gradients is −1. We have: x2 +xy + y2 = 7. First let us check that (1,2) and # (-1,3) lies on the curve: (1,2) ⇒ 1 +2 +4 = 7. ( − 1,3) ⇒ 1 ... WebSep 26, 2006 · To find a tangent line: 1) Find the derivative of your function. The derivative gives you the slope of the function for any given x. 2) Find a point on the curve: an x 0 and its corresponding y 0. 3) Use point-slope form to combine the point and slope into a single equation. In this case, the x 0 is arbitrary.
WebThe slope of the tangent line is 1, so d y d x = 1, and therefore from 2 x + 4 y d y d x = 0 we conclude that 2 x + 4 y = 0, meaning that x + 2 y = 0. But also x 2 + 2 y 2 = 1. Substitute − 2 … WebJul 5, 2024 · Slope of the tangent line to the curve at x=2 is 4, we get y=4x+c The tangent line passes through the point (2,4) and hence substituting in the above equation we get: 4 = 4 (2)+c c = -4 The final equation of the tangent line is y = 4x-4 3. f (x) = x^3+2x+1 This function is shown below, along with its tangent lines at x=0, x=2 and x=-2.
