If we remember the graph of cosine, it has points where it has a y value of zero. At those points this tangent identity would be trying to divide by zero, which is undefined. Your calculator will probably display “error” if you try it! This is how you know you’ve found an ...

Equations and Definitions for How to Graph a Cotangent Function of the Form y = a cot b(x-h) + k Cotangent Function:The cotangent function is one of the 6 trigonometric functions and is the inverse of the tangent function. The standard form of a cotangent function is...
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
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...

angles, such as the sine, cosine and tangent. Calculators can be handy in finding these functions because they have sin, cos and tan buttons. However, sometimes you won't be allowed to use a calculator on a homework or exam problem or you might simply not have a calculator. Don't ...
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). ...
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 at x = 2, though you may want to go through the calculus/algebra anyway to prove...
