Find the point(s) on the graph of f where the tangent line is horizontal. (If an answer does not exist, enter DNE.) f(x) = (x)/ (x^2 + 4)

Find the point(s) on the graph of f where the tangent line is horizontal. (If an answer does not exist, enter DNE.) f(x) = (x)/ (x^2 + 4)

Find the slope and an equation of the tangent line to the graph of the function f at the specified point. f(x) = √x + (1/√x); (25,26/5) slope= equation y =

Find dy/dx for x2y4 + √2x + 5y=7 Show that the point (x,y) = (2,1) lies on the curve defined by the equation above and find the slope of the tangent line at this point....

tangent of an angle shows the gradient of a straight line but what this itself shows when it is graphed?

I was given this homework problem, but I'm not even sure what it's asking me to do. Find all points on the curve y=8tanx, [-π/2,π/2], where the tangent line is parallel to y=16x...

If Dave is standing at (12,0) next to a silo of cross-sectional radius r = 7 feet at the indicated position, his vision will be partially obstructed. Find the portion of the y-axis that...

In the middle of solving this implicit function/using implicit differentation to find its tangent line, this is what I have so far: Original function: y^3+x^3-2xy=8 (find tangent...

So I'm supposed to graph the given function at the tangent line at the given point, which I know how to do with an explicit/one part function but not an implicit/two part function. The function...

How would i graph this? We are learning "graphing tangent function". I know you find the amplitude,period, subperiod then you do y=1/2tan2(0) which gives you y=0. Then you do that again...

came across this problem and it is suppose to be graphed in degrees. I have only graphed in radians. How do I do it?
