The first chapter is talking about how they brake up a degree into minutes and minutes into seconds....
Is this concept important to understand. And how will it help me with other harder trig problems???

Hi Miike012! :smile:

It doesn't matter at all, except for surveying or navigation on the Earth's surface, or for measuring the positions of stars …

in most cases, we just use degrees or radians (perhaps you haven't done radians yet? :wink:) to the required number of decimal places.

But that won't help you if you're trying to navigate with a map marked in minutes and seconds, so yes you'd better understand it! :biggrin:

If you don't understand it, then it is important that you learn it. If you already know and understand the concepts then it should be a piece of cake.

Now, what is your question?

Ah … telling you that would spoil the surprise! :wink:

An angle is a piece of cake! :smile:

Well I guess I will just have to read and find out...

The book that I am reading from is called plane trig by s.l. loney...
I heard this book was a good book?
But what makes it better than another book? Does it go more indepth, or have more theorems?

If you really want to go in depth with trig i would recommend Gelfand's trigonometry once you get the basics down
