How to find tangent line.
There is no short answer since this is a general question. You must have a differentiable function to find a tangent line to a curve. So, let f (x) be the function for the curve. And let f' (x) be the derivative of f (x). Finally, let x=a be the value at which we want the tangent line: T (x)=f (a)+f' (a) (x-a) Note that this is also the formula ...

May 16, 2019 · Therefore, our tangent line needs to go through that point. This tells us our tangent line equation must be y=16 (x-2)+10 y=16x-32+10 y=16x-22. And that’s it! We know that the line will go through the point on our original function. And we know that it will also have the same slope as the function at that point.

Tangent Lines and Secant Lines. (This is about lines, you might want the tangent and secant functions) A tangent line just touches a curve at a point, matching the curve's slope there. (From the Latin tangens "touching", like in the word "tangible".) A secant line intersects two or more points on a curve. (From the Latin secare "cut or sever")

It's very important to remember that the equation for a tangent line can always be written in slope-intercept or point-slope form; if you find that the equation for a tangent line is y = x 4*x²+e + sin (x) or some such extreme, something has gone (horribly) wrong. The slope of a tangent line will always be a constant.The equation of the tangent line is given by. y −y0 = f′(x0)(x − x0). y − y 0 = f ′ ( x 0) ( x − x 0). For x x close to x0 x 0, the value of f(x) f ( x) may be approximated by. f(x) ≈ f(x0) +f′(x0)(x −x0). f ( x) ≈ f ( x 0) + f ′ ( x 0) ( x − x 0).
