| Function Type | Derivative Formula | Example | How to Remember | |---------------|-------------------|----------|-----------------| | (a^x) | (\fracddx a^x = a^x\ln a) | (\fracddx3^x = 3^x\ln 3) | Derivative of (e^x) is itself; the extra (\ln a) appears for other bases. | | Natural Exponential (e^x) | (\fracddxe^x = e^x) | (\fracddxe^2x=2e^2x) (chain rule) | Keep “(e) is its own derivative”. | | Natural Logarithm (\ln x) | (\fracddx\ln x = \frac1x) | (\fracddx\ln (x^2+1) = \frac2xx^2+1) | Chain rule adds the inner derivative. | | Logarithm base (a) (\log_a x) | (\fracddx\log_a x = \frac1x\ln a) | (\fracddx\log_10x = \frac1x\ln 10) | Convert to natural log if you forget. | | Sine & Cosine | (\fracddx\sin x = \cos x), (\fracddx\cos x = -\sin x) | (\fracddx\sin(2x)=2\cos(2x)) | Use the unit circle to recall sign changes. | | Tangent & Cotangent | (\fracddx\tan x = \sec^2 x), (\fracddx\cot x = -\csc^2 x) | (\fracddx\tan(3x)=3\sec^2(3x)) | Remember (\sec^2 = 1+\tan^2). | | Sec & Csc | (\fracddx\sec x = \sec x\tan x), (\fracddx\csc x = -\csc x\cot x) | (\fracddx\sec(5x)=5\sec(5x)\tan(5x)) | Derivatives of reciprocal trig functions involve the other. | : Limits, continuity, and the rules of differentiation
by B.C. Das and B.N. Mukherjee is a definitive textbook for undergraduate students in Indian universities. Often paired with their companion text on Integral Calculus , this book is valued for its traditional, rigorous approach to mathematical foundations.
