Limits

limh4Dx  Really shows the derivative is the limit of the diference quotient. Use this one!!
Derivatives

derivativeTests  Derivative Tests & DerAnyFx

DerAnyFx  Derivative of Any Function
* One may trace the function and see coordinates displayed.
* One may edit the function. * One may graph the approximate derivative function.
1  f(x) w/tangent line
2  f(x) & TRACE
3  any f(x): x, f(x), f'(x), f''(x)
4  sin(x): x, f(x), f'(x), f''(x)

DerCos  Derivative of Cosine

Dere2x  Derivative of the exponential

Derlnx  Derivative of the Natural Log

DerReciprocal  Derivative of the Reciprocal Function

DerSqrt  Derivative of the Square Root

DerReciprocal  by use of a tangent line

DERe2x  by use of a tangent line

DerSqrt  simple curve and tangent. Could make it fancy.

DerSquare  simple graph w/tangent of x^{2}. Could make it fancy.
Trig Derivatives

DerivSin  full blown 4page sketches ** Use this

DerSin  simple sine and tangent line. Use other DerivSin.

DerCos  cosine graph, movable tangent line w/equation,
* m derived by simple m formula (h=.01), * "derivative" may be graphed.

DerivCos  display cosine graph and entire difference quotient triangle (not the best)

DerTan  tangent function & tangent line graphed, actual derivative function is provided & may be graphed.
