Question

Find the value of the derivative of
f(θ) = 2 sin θ − θ
at (0,0)

Answer 1

f(x) = 2 sin x - x
f'(x) = 2 cos x -1
At ( 0 , 0 ) , x-coordinate = 0 ,
f'(x) = 2 cos 0 - 1 = 1

Answer 2

if you dont understand some parts just tell :D

Answer 3

!o i got it! Thank you! I saw the θ and freaked for a second lmao

Answer 4
