We talked briefly about a question in class, which you asked me to submit by this form for a full answer. I concluded that sine and inverse sine were not inverse functions based on the trials that I did; however, you said that you would explain that they actually are inverse functions, but they are not inverse functions for all numbers.

I went ahead and posted an answer to this question along with my response to the question you asked over the weekend.

For the problem: If a(n)=a(n-1)+b, with a(0)=5, then if a(250)=0, what is the value of b?"" I don't understand how to find b, as the other recurrence relation problems that I have worked had only n and a as variables.

Under the Precalculus access number 23-24-242 check out the following link for an explanation:

Let me know if anything there is not clear.
