Urgent help appreciated!https://ask.sagemath.org/question/10132/calculus-graphing-urgent-help-appreciated/A math student writes a proof of the derivative of a certain trigonometric function. The last line she writes before stating her conclusion is...
**d/d?(sin(?+?/2))=cos(?+?/2)**
These are the graphs of sin(?+?/2) and cos(?+?/2)
**sin(?+?/2)** = http://www.wolframalpha.com/input/?i=sin%28theta%2Bpi%2F2%29&lk=4
**cos(?+?/2)**= http://www.wolframalpha.com/input/?i=cos%28theta%2Bpi%2F2%29&lk=4&num=1
