- By solving the two equations you will get a point (x,y) which lies on both the curve and the straight line. 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.

Sep 3, 2018 · $\begingroup$ derive $f(x)=e^{x-y}(2x^2+y^2)$. When you get $f'(x)$ plug in the value $x=1$ to get a y value. That will be the gradient of the tangent to the curve $f(x)$. Then write $y=mx+b$, filling in $m$ with whatever you got for the gradient. Then plug in $(1,0)$ and solve for $b$ $\endgroup$ –

Feb 22, 2019 · The text book question is $f(x,y)=xy$, find the gradient vector $\nabla f(3,2)$ and use it to find the tangent line to the level curve $f(x,y)=6$ at the point $(3,2)$.
find the points (a, b) (a, b) of the plane that satisfy the tangent of the level curve M = f(a, b) M = f (a, b) in the point (a, b) (a, b) passes through (0, 1) (0, 1). I tried solving this simply by using the equation of the tangent to a level curve: fx(a, b)(x − a) +fy(a, b)(y − b) = 0 f x (a, b) (x − a) + f y (a, b) (y − b) = 0 ...

The tangent line to a curve at a given point is the line which intersects the curve at the point and has the same instantaneous slope as the curve at the point. Finding the tangent line to a point on a curved graph is challenging and requires the use of calculus; specifically, we will use the derivative to find the slope of the curve.
