  • Waiting for answer How do you use the limit definition to compute the derivativ...

    The definition of derivative in a generic point ##(x,f(x))## is: ##lim_(hrarr0)(f(x+h)-f(x))/h=f'(x)##. So: ##lim_(hrarr0)(cos(3(x+h))-cos3x)/h=lim_(hrarr0)(cos(3x+3h)-cos3x)/h=## than, using the formula sum-to-product : ##costheta-cosphi=-2sin((theta+phi)/2)sin((theta-phi)/2)##, ##=lim_(hrarr...
