Question

What is the deravative of sin(678)

Answer 1

Answer:

cos (678)

Step-by-step explanation:

The derivative of sin (x) = cos (x)

Hence, substituting the value of x as 678, we get the derivative of sin (678) as cos (678).

Thus: Cos (678) = cos (720 - 42) = cos (42) = 0.743 (apply trignometric identy)
