Breaking Down Degrees: Is It Important?

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?

Hi Miike012!

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! ​

Havnt looked at it yet... but ill be on radians in the next two pages lol.. what is a radian?

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!

An angle is a piece of cake! ​

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

 

[Miike012]

Thank you... Do you know of a good indepth alg book...?

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.
