Tru dat
After the derivation all you get is:
>Sin of an integer multiple of pi
>And a cos of an integer multiple of pi plus pi over 2
Inb4 amerimutt with burgermart education somehow got 6/pi or some far off shit

How fucking retarded are you that you can get an answer where pi is the divisor of a fraction?

>>6850026
assuming x = pi:
δ/δx(7sin(7x-x/2)+cos(3x)) = 7sin(7x-x/2)+cos(3x)/x
δ(7sin(7x-x/2)+cos(3x))/δx
7sin(7x-x/2)+cos(3x)/x
sin(7x-x/2=sin(x/2)
7sin(x/2)+cos(3x)/x
7sin(x/2)+cos(x)/x
then use the trivial identity sin(x/2)=1
7*1-1/x
simplify to 6/x
then if you do the literal result, it ends in ~1.909

The answer's zero if I remember correctly how to do derivatives of trigonometric functions.

δ in δ/δx isn't an unknown, it is... I dunno actually what, basically it means that you are supposed to do a derivative
