What is a tangent function in Excel?

Tangents are numerical entities, as distinguished from test strings, for example. A tangent function is a smooth but discontinuous function. It is a function of a value usually an angle. Excel does not draw continuous functions. One can draw lines on the computer screen or print out that screen.

How do you find the tangent of a graph?

The equation for the tangent line is “y – Y = dy/dx * (X) * (x – X).”. The point (X,Y) is where you’re calculating the tangent line. The variable “dy/dx” is the result of the “SLOPE” function, representing the slope of the tangent line.

How to find the slope of a tangent line in Excel?

Given a function, you can easily find the slope of a tangent line using Microsoft Excel to do the dirty work. That is to say, you can input your x-value, create a couple of formulas, and have Excel calculate the secant value of the tangent slope.
