WebMay 22, 2024 · Here is a trick I use to remember the derivatives and antiderivatives of trigonometric functions. If you know that \begin{align} \sin'(x) &= \cos(x) \\ \sec'(x) &= \sec(x)\tan(x) \\ \tan'(x) &= \sec^2(x) \, . \end{align} then the derivatives of $\cos$, $\cot$, and $\csc$ can be memorised with no extra effort. These functions have the prefix co- in …

1. Derivatives of the Sine, Cosine and Tangent Functions
WebTo remember which derivative contains the negative sign, recall the graphs of the sine and cosine functions. At x = 0, sin(x) is increasing, and cos(x) is positive, so it makes sense that the derivative is a positive cos(x). On the other hand, just after x = 0, cos(x) is decreasing, and sin(x) is positive, so the derivative must be a negative ...
