Answer 2

@Directrix

Answer 3

i got to here

f(x) = cos (x) = 1/2

f'(x) = -sin(x) = - rad 3 /2
f''(x) = cos (x) = -1/2
f'''(x) = sin (x) = rad 3 /2

Answer 4

come back D: @IrishBoy123

Answer 5

oh so then how should it be ?

Answer 6

ik there is formula first but we find 3 derivatives of this right?

Answer 7

please help ...@steve816

Answer 8

So far your derivatives are fine. Can we start to define a rule for \( \frac{d^nf}{dx^n}\)?
