I'm just wondering if someone can give me a few pointers here so that I can understand the concepts behind trigonometry program for ti 84+. I find solving problems really difficult. I work part time and thus have no time left to take extra tutoring . Can you guys suggest any online resource that can assist me with this subject?

You’re not alone. As a matter of fact , I had the same woes just before I found something very helpful . Have you encountered Algebrator? If you have not heard anything about this great piece of program yet, let me enlighten you a bit about this software. This is a program that helps you to answer math problems and at the same time you could learn from it because it displays a step-by-step procedure of answering the problem. It helped me in my woes in algebra and my marks significantly improved since I used this. Be reminded that it does not only display the answer but it helps you learn how to solve the problem that makes it very educational.

I would advise using Algebrator. It not only assists you with your math problems, but also displays all the required steps in detail so that you can improve the understanding of the subject.
