Iera K. WebIn this case, you may do this by using some easy estimates on the factorial. Use sin ( x + h) = sin ( x) cos ( h) + sin ( h) cos ( x). sin ( x + h) − sin ( x) h = sin ( x) ( cos ( h) − 1) h + sin ( h) cos ( x) h. you get that sin ′ ( x) = cos ( x). For cos you get the hint cos ( x + h) = cos ( x) cos ( h) − sin ( x) sin ( h) $.
