Today John Henry showed us some strategies for proving identities. This is also in the book chapter 3.2.
The first strategy we learned was for proving an identity when you have fractions.
Multiply denominator and numerator by the numerator of the opposite side.
Cos^2+sin^2=1 - Pythagorean Identity.
Second strategy - Splitting Fractions with + or - in numerator.
Cos^2+sin^2=1 - Pythagorean Identity.
Second strategy - Splitting Fractions with + or - in numerator.
Also below this post Irfan shared a great website on all the strategies for proving identities. Looking at that website was the most helpful for me. I recommend anyone who is having trouble with these to look at this website. It's very simple and well written. A good way to memorize these strategies and identities is flash cards! We have a final coming up soon so I suggest you do that!
