Differentiation of Trigonometric Functions

    • \frac{{\text{d}}}{{{\text{dx}}}}\left( {\sin {\text{x}}} \right) = \cos {\text{x}}

    • \frac{{\text{d}}}{{{\text{dx}}}}\left( {\cos {\text{x}}} \right) = - \sin {\text{x}}

    • \frac{{\text{d}}}{{{\text{dx}}}}\left( {\tan {\text{x}}} \right) = {\sec ^2}{\text{x}}

    • \frac{{\text{d}}}{{{\text{dx}}}}\left( {\cot {\text{x}}} \right) = - \cos e{c^2}{\text{x}}

    • \frac{{\text{d}}}{{{\text{dx}}}}\left( {\sec {\text{x}}} \right) = \sec {\text{x}}\tan {\text{x}}

    • \frac{{\text{d}}}{{{\text{dx}}}}\left( {\cos ec{\text{ x}}} \right) = - \cos ec{\text{ x}}\cot {\text{x}}
