WebSep 7, 2024 · The derivative of the sine function is the cosine and the derivative of the cosine function is the negative sine. d dx(sinx) = cosx d dx(cosx) = − sinx Proof Because the proofs for d dx(sinx) = cosx and d dx(cosx) = − sinx use similar techniques, we provide only the proof for d dx(sinx) = cosx. WebDifferentiation Interactive Applet - trigonometric functions. In words, we would say: The derivative of sin x is cos x, The derivative of cos x is −sin x (note the negative sign!) and The derivative of tan x is sec 2x. Now, if …

WebIf f ( x + k) = f ( x) then sin ( 2 x + 2 k) = sin 2 x so the period of sin would be 2 k or smaller. So 2 k is not smaller than 2 π.) Your confusion lies in you think we are adding 2 π to 2 x into the argument of sin it makes the period 2 π. True; it makes the period of SINE (x) 2 π.
