## Homework Statement

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?

If you already know and understand the concepts then it should be a piece of cake.

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? ) 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!

Ah … telling you

An angle *is* a piece of cake!

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?

I've been working through Algebra by the same author for few weeks. Emphasis is on proving things as opposed to computations so if math is your interest I would highly recommend it. However if you're looking to apply it to physics or engineer, etc. it may be a little too tedious.
