How To Easily Remember the Unit Circle

I work in a walk-in tutor lab at my university and one of the other tutors showed me this a couple years back and it has changed my life.

First, you make a table that looks like this.

Then, go ahead and add in some nice denominators of 2 in every entry in the table.

Then give yourself some nice square roots on the numerators.

Alright – now we’re going to fill it in. The only value you have to remember is that sin(0)=0. So we put 0 in the numerator for 0 in the sine column. Then we just count up as we move down.

Then we do the opposite in the cosine column.

Then we simplify!

And voila – a beautiful unit circle table. 

hey reblog this if you think girls can study and excel in computer science

The honest confession :)

kids, when you’re choosing your college schedule, you’ll hear a voice saying “just take the 8AM class. it won’t be that bad. you’ve done it for this long” that’s the devil talking

The thing about programming is that it teaches you that you can flip-flop between feeling like a genius and an idiot considerably faster than you ever expected.

I googled science pick-up lines and I was not disappointed

You’re so hot, you denature my proteins. 

Do you have 11 protons? ‘Cause you’re Sodium fine!  

You make my anoxic sediments want to increase their redox potential. 

I’m more attracted to you than F is attracted to an electron. 

We fit together like the sticky ends of recombinant DNA. 

You’re hotter than a bunsen burner set to full power. 

If I were a neurotransmitter, I would be dopamine so I could activate your reward pathway. 

According to the second law of thermodynamics, you’re supposed to share your hotness with me. 

How about me and you go back to my place and form a covalent bond?

I wish I were Adenine because then I could get paired with U.

If you were C6, and I were H12, all we would need is the air we breathe to be sweeter than sugar.

I want to stick to u like glue-cose.

You must be the one for me, since my selectively permeable membrane let you through.
