Find the derivative of the function s = sin(3t)-
cos(7t).
Solution:-
Use the rules of differentiation to find .
s = sin(3t)-
cos(7t).
=
To find sin(3t) and
cos(7t), use the Chain Rule.
(sin(3t)) = 3 cos(3t)
To find (cos(7t)), use the Chain Rule.
(cos(7t)) = -7sin(7t)
Substitute the expressions for (sin(3t)) and and
.
=
=
Thus,
