Horizontal lines have a slope of zero. Therefore, when the derivative is zero, the tangent line is horizontal. To find horizontal tangent lines, use the derivative of the function to locate the zeros and plug them back into the original equation. Horizontal tangent lines are important in ...
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 is horizontal. To find horizontal tangent lines, use the derivative of the function to...
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) =...
Today we’re exploring tangent in trigonometry, where it is one of the “big three” trigonometric functions, along with sine and cosine. Like those two functions, it can be used to find the measure of a side or the measure of an angle in a right triangle. But it’s also a bit ...
Now, we will see how to find the critical points from the graph of a function. The following points would help us in identifying the critical points from a given graph.We know that the points at which the tangents are horizontal are critical points. So at all such critical points, the ...

Moreover, this also implies that the function \(f\left( {x,y} \right)\) has a horizontal tangent plane at the point \(\left( {{x_0},{y_0}} \right)\) and helps us to determine extrema. Relative Minimum A point \(\left( {{x_0},{y_0},f\left( {{x_0},{y_0}} \righ...
