F(x) = cos x is --------- function in [0, π] increasing , decreasing

1.	F(x) = cos x is --------- function in [0, π] increasing , decreasing or both
Answer» ong>Step-by-step explanation: X∈(0,π) ⇒sinx>0⇒−sinx<0 ⇒f ′ (x)<0 so f(x) is STRICTLY decreasing on (0,π)

Answer»

ong>Step-by-step explanation:

X∈(0,π)

⇒sinx>0⇒−sinx<0

⇒f

′

(x)<0

so f(x) is STRICTLY decreasing on (0,π)
