Question:medium
The function \( f(x) = \sin x - kx - c \), where \( k \) and \( c \) are constants, decreases always when
The function \( f(x) = \sin x - kx - c \), where \( k \) and \( c \) are constants, decreases always when
Show Hint
For “always” conditions, always test using maximum/minimum values of trigonometric functions.
