I'm not sure what you mean by . Is it
I know that the remainder of the Maclaurin series is given by
In this case, it would be
Use the Maclaurin series to make the S4 approximation of sin 3. What do you know about the error of this approximation?
The Maclaurin series is of sin(x) in the form of x - (x^3)/3! + (x^5)/5! .................
My book says the actual value of sin 3 lies in the interval of (0.0910714286, 0.1453125) but I don't understand why it shouldn't be (0.0368303572, 0.1453125) because a5 (which is the error bound) equals 0.0542410714. Why didn't the book include the left side of the error bound while some answers are that way??? I don't get it.
I'm begging you to help me, my book does a terrible job explaining approximation topics. You're my only hope.
