Solve a(n) = a(n-1)

Evaluate

a (n) = a (n - 1)

Take the derivative of both sides

a^{'} (n) = \frac{d}{d n} (a (n - 1))

Calculate

a^{'} (n) = \frac{d}{d n} (an - a)

Use differentiation rule \frac{d}{d x} (f (x) \pm g (x)) = \frac{d}{d x} (f (x)) \pm \frac{d}{d x} (g (x))

a^{'} (n) = \frac{d}{d n} (an) + \frac{d}{d n} (- a)

Calculate

More Steps

a^{'} (n) = a + \frac{d}{d n} (- a)

Use \frac{d}{d x} (c) = 0 to find derivative

a^{'} (n) = a + 0

Solution

a^{'} (n) = a
