Write one rule of derivatives for a  function?

Fariba's Example : d(e^x)/dx= e^x

# data[].attributes.body
d/dx f(g(x)) = f'(g(x)).g'(x)

# data[].attributes.body
Power Rule

# data[].attributes.body
Quotient Rule. Evan

# data[].attributes.body
d cos(x)/dx = -sin(x)
dtan/dx = sec^2(X)

# data[].attributes.body
d/dx (sinx) = cosx

# data[].attributes.body
J(x) = f(x)*g(x)
J’(x) = f’(x)*g(x)+g’(x)*f(x)

# data[].attributes.body
d cos x/dx = -sin x

# data[].attributes.body
f''(x)= +  , f(x) is concave up
g''(x) = -   , g(x) is concave down

PRoduct rule d(uv)/dx=u.dv/dx+v.du/dx

# data[].attributes.body
(sec(x))' = sec(x) * tan(x)
