    • How do you find the equation of a normal line?

      To find the equation of the normal line, take the derivative of the tangent line at the point on the curve. The slope of the normal line will be the opposite reciprocal of the derivative of the tangent line. To unlock this lesson you must be a Study.com Member.

    • How do you calculate the tangent of a curve?

      Find the value on the horizontal axis or x value of the point of the curve you want to calculate the tangent for and replace x on the derivative function by that value. To calculate the tangent of the example function at the point where x = 2, the resulting value would be f'(2) = 2*2 = 4. This is the slope of the tangent to the curve at that point.

    • How do you know if a line is tangent to a curve?

      if you got more than one point then this line will be intersecting and not a tangent to the curve. then by finding the first derivative of the curve and substituting with the value of the point#(x,y)#. if it's value is equal to the slope of the straight line then this line is its tangent.

      The slope of a tangent line at a point on a curve is known as the derivative at that point ! Tangent lines and derivatives are some of the main focuses of the study of Calculus ! The problem of finding the tangent to a curve has been studied by numerous mathematicians since the time of Archimedes. Archimedes Definition of a tangent line:

    • Finding the Equation of a Tangent Line

      The tangent line appears to have a slope of 4 and a y-intercept at –4, therefore the answer is quite reasonable. Therefore, the line y = 4x – 4 is tangent to f(x) = x2 at x = 2. Here is a summary of the steps you use to find the equation of a tangent line to a curve at

      Therefore the normal to surface is Vw = U2x, 4y, 6z). At the point P we have Vw| P = U2, 8, 18). Using point normal form, the equation of the tangent plane is 2(x − 1) + 8(y − 2) + 18(z − 3) = 0, or equivalently 2x + 8y + 18z = 72. 2.

      Tangent lines to conics Apollonius’ approach to tangent lines for conics is typical of Greek geometry, and it is based upon the fact that such lines meet the curves only at the point of contact. This viewpoint is evident in elementary geometry, where one views a tangent line to a circle as a line which meets the circle in exactly one point.
