Explanation:
So here we have a trig function and whenever we see trig functions, the first thought that should pop into our head is that we need to use the chain rule. So to start, we will take the derivative of the outside, which in this case would be the
However, the chain rule then requires we multiply this derivative by the derivative of the inside part of the function,
Explanation:
The derivative of cosine is negative sine. So
But according to the chain rule, you have to multiply this by the derivative of the contents inside the parentheses.
The derivative of
So the velocity function would look like:
