The derivative of cos x is the negative of the sine function that is sin x Derivatives of all trigonometric functions can be calculated using the derivative of cos x and derivative of sin x The derivative of a function characterizes the rate of change of the function at some point.

$$ \quad\cos x \leq \frac{\sin x}{x} \leq 1 \quad \displaystyle\forall x \in ]\frac{\pi}{2} 0[ \cup ]0 \frac{\pi}{2}[ $$ By using the Squeeze Theorem $$ \lim _{x \rightarrow 0} \frac{\sin x}{x}= \lim _{x \rightarrow 0} \cos x=\lim _{x \rightarrow 0} 1 = 1 $$ we conclude that $$ \lim _{x \rightarrow 0} \frac{\sin x}{x} = 1 $$ Also in this section Proof of limit of sin x / x =.
