Thread: exponential functions

f(x) = e^-1/(2x)
f(x) = e^-1/(2x)*(-1/2)
f'(x) = -1/2e^1/2x

is that correct?

Hello, startingover!

f(x) .= .e^-1/(2x)

f'(x) .= .e^-1/(2x)(-1/2) ?

f'(x) .= .-1/2e^1/2x

is that correct? . . . . no

The exponent is: .-1/(2x) .= .-½ x^{-1}

Its derivative is: .½ x^{-2} .= .1/(2x²)
