A horizontal tangent line is a mathematical feature on a graph, located where a function's derivative is zero. This is because, by definition, the derivative gives the slope of the tangent line. Horizontal lines have a slope of zero. Therefore, when the derivative is zero, the tangent line...

Determine the coordinates of the indicated point by plugging the value of x into the function. For example, to find the tangent line where x = 2 of the function F(x) = -x^2 + 3x, plug x into the function to find F(2) = 2. Thus the coordinate would be (2, 2). Find the de...
A tangential line is a straight line on a graph that runs tangent to a curved line made up of data points. Excel has the ability to create a trendline automatically, or you can manually draw the tangential line on the graph. The tangential line is drawn touching a curved line so that a...
How to Find the Tangent on a Graph in Excel. The tangent is defined as the single point where a straight line meets a curved surface. The tangent can be determined with a collection of mathematical formulas but is most commonly determined by dividing the
If the tangent line to the graph is above the graph, the function is concave, and if the tangent line is below the graph, the function is convex, The concavity of a function, when the graph is not given, is determined by the second derivative test, ...
A linear equation produces a straight line in a graph. The general formula for a linear equation is y = mx + b, where m stands for the slope of the line (which can be positive or negative) and b stands for the point that the line crosses the y-axis (the
Graphing can sometimes help you see where a vertical tangent line might be. Graph the function—so you can see where the graph might have a vertical tangent. I usedthis handy HRW calculatorto get the above graph of y = √(x – 2). It’s gairly clear that there’s a vertical tangent...
We use tangent to find the length of the side of a right triangle that is adjacent to an acute angle with a known measure as long as we know the measure of the side opposite that angle. When we graph tangent functions, we see that the y-values have a range of negative infinity to ...
Example Problem 2- How to Graph a Cotangent Function of the Form y = a cot b(x-h) + k Sketch a graph of the functiony=cot(12(x−π)−1. Step 1:First, we find the equations of two of the asymptotes of the function and the period of the function. ...
