RE: Hp Prime - CAS inconsistent derivatives of sin, cos, tan
(05-29-2014 10:40 AM)cdecastro Wrote: This is correct. The derivative rules d(sin(x))=cos(x) etc.. only hold when the angle is measured in radians. If the angle is in degrees the appropriate rule is found by applying the chain rule.Correct $$(g\circ f)'=g'\circ f*f'\\ \sin { (a*x)'=cos(a*x)*a } $$ While converting from degree to radian you get the conversion factor $$a=\frac { \pi }{ 180 } $$ |
