First, the derivation algorithm
Constant factor rule: if f(x) is a function and c is a constant, then d/dx(cf(x)) = c(d/dx(f(x)).
Addition and subtraction: if f(x) and g(x) are two functions, then d/dx (f (x)+g (x)) = d/dx (f (x)+d/dx (g (x)), d/dx (f (x)-g (x).
Multiplication rule: if f(x) and g(x) are two functions, then d/dx (f (x) g (x)) = f (x) d/dx (g (x))+g (x) d/dx (f (x)).
Division rule: if f(x) and g(x) are two functions, then d/dx (f (x)/g (x)) = [g (x) d/dx (f (x))-f (x) d/dx (g (x)] [g (x)
Second, the derivative formula
The derivative of a constant function is 0, that is, d/dx(c) = 0, where c is a constant.
The derivative of the power function is NX (n- 1), that is, d/dx (x n) = NX (n- 1), where n is a positive integer.
The derivative of exponential function is e x, that is, d/dx (e x) = e x.
The derivative of logarithmic function is 1/x, that is, d/dx (lnx) =1/x.
Third, the derivative of trigonometric function is:
The derivative of sinx is cosx, that is, d/dx (sinx) = cosx;
The derivative of cosx is -sinx, that is, d/dx (cosx) =-sinx;
The derivative of tanx is sec 2x, that is, d/dx (tanx) = sec2x;
The derivative of cotx is -CSC 2x, that is, d/dx (cotx) =-CSC 2x.
Four, the derivative of the inverse trigonometric function is:
The derivative of arcsinx is1√ (1-x 2), that is, d/dx (Arcsinx) =1√ (1-x 2);
The derivative of arccosx is-1√ (1-x 2), that is, d/dx (arccosx) =-1√ (1-x 2);
The derivative of arctanx is1/(1+x 2), that is, d/dx (arctanx) =1/(1+x 2).
