Sine, Cosine, Tangent

[yvr girl]

I'm having a math mental block. I can't remember this stuff - it's gone. What the hell are they? Believe it or not, I did well in math.

[KitchenWitch]

1. Unused math becomes forgotten math

I bet if you opened a math book, it would all come back to you.

[JVS]

2. They are called Sine and Cosine

Tangent you got right. Now all you need to do is remember: Oscar Had A Hunk Of Ass. You should be fine.

[yvr girl]

3. You know I thought that was how they were spelled

but I googled tangent and the three words showed up as I spelled them. Damn Internets.

"Oscar Had A Hunk Of Ass." Huh?

[LearnedHand]

4. Oscar...

Opposite over hypotenuse (sine: "oscar had")
Adjacent over hypotenuse (cosine: "a hunk")
Opposite over adjacent (tangent: "of ass")

Oh, they're trig ratios.

[JVS]

7. These relations are true for the trig functions of angles...

on right triangles. Just pointing that out for those reviewing their trig.

[deadparrot]

17. I learned SOHCAHTOA

Sine=Opposite/Hypotenuse
Cosine=Adjacent/Hypotenuse
Tangent=Opposite/Adjacent

6. I remember SOHCAHTOA

sine - opposite over hypotenuse

cosine - adjacent over hypotenuse

tangent - opposite over adjacent

At least that's my dim memory of calculus

[JVS]

8. Oscar Had A Hunk Of Ass is a much better way to remember

Sohcahtoa is ok, but it doesn't carry an indellible meaning

Also when learning Latin it is good to remember the case tables by saying.

Never Get Done ACCepting Anal Veneration (I.e. being kissed up to)

That lets you remember the nominative, genitive, dative, accusative, ablative and vocative cases.

9. Some old hippie

Caught another hippie
Tripping on acid.

[JVS]

10. And for the Latin?

[XemaSab]

12. ?

.

[JVS]

13. How do you remember the order of the cases for declesion?

[XemaSab]

16. Normative

Genital
Dating
Accusatory
Absolut
Vituperitive

That's the cases, right? RIGHT?

[JVS]

20. WRONG! Do it AGAIN!

[XemaSab]

23. Amo,

Amiss,
Remit,
Pablanos,
Clematis,
Gallant.

11. Of course, vulgarity is always preferable...

...in the military some people use "Be My Little General" to remember the ranks of generals from lowest to highest (brigadier, major, lieutenant, general), however, I always preferred the more vulgar "Bite My Left Gonad".

[Telly Savalas]

14. That's the pneumonic I was taught 20 years ago, and it still sticks.

[SW FL Dem]

15. It's long gone, and I was an A math student

even scarier, I now have a kid in high school. I took Calculus in 1974. I hope he gets it so I don't have to relearn this stuff.

[mzteris]

19. When my daughter

was in highschool, she was yelling, "Why do I have to learn this stuff anyway? I'll never use it again!"

My answer?

"Yes, you will. You'll have to help your kids with THEIR homework some day!"

[Tom Kitten]

18. so what happened to yvr girl, anyways?

I hope you guys didn't help make her mental block bigger!

[tallahasseedem]

21. Oh man, I love me some Trig...

I loved that class!!!

[swimboy]

22. I got the ratios under my belt and they hit me with the unit circle.
