WebThis interesting pattern of derivatives involving sine and cosine is related to the fact that e^x is its own derivative and that e^(ix) = cos(x) + i*sin(x) (Euler's Formula). These two facts are in some sense the math hiding behind Justin L's more physical explanation, which you might well find more intuitive. WebEach of these functions are derived in some way from sine and cosine. The tangent ofxis defined to be its sine divided by its cosine: tanx= sinx cosx : The cotangent ofxis defined to be the cosine ofxdivided by the sine ofx: cotx= cosx sinx : The secant ofxis 1 divided by the cosine ofx: secx= 1 cosx ;
