The Five Biggest Contradictions in Fitness

Itís no secret that when people contradict themselves, it has the effect of making the flaws in their actions or statements seem glaringly obvious. But what about when WE ourselves get caught contradicting ourselves by someone else?

    Anyone good at math?

    I need a few answers....

    using identities find the values
    1. sin* = -6/7 , find cos*

    2. sec^2 pie/12 - tan^2 pie/12

    for # 2 i think you have to deo something with the equation cos^2 X = 1 - sin^2 X

    Find exact value
    3. cos* = -12/13 , angle (*) in quad III

    4. Tan* = -3 , cos *>0

    I remember that stuff, not enough to help though. I'm so glad they teach such useful things in school.

    Do you just want exact answers? What do you mean by "cos*" ? What's the * for?

    Okay, well, if sin theta is negative, theta is in quadrant 3 or 4.

    Constructing the reference triangle, the sides are as follows:

    Opposite: 6
    Hypoteneuse: 7
    Adjacent: Sqrt(49-36) = Sqrt(13)

    So, if theta is in quadrant 3, cos theta is negative sqrt(13)/7

    If theta is in quadrant 4, cos theta is positive sqrt(13)/7

    This is just the pythagorean identity. It is identically equal to one. You need to learn your identities.

    Use cos theta = 12/13 to find the reference angle, then add it to 180 degrees

    Quote Originally Posted by accuFLEX

    Tan is negative in quadrants II and IV

    If cos is positive, this eliminates quadrant II

    Since tan theta = -3, the reference triangle has opposite = 3, adjacent = 1, hypoteneuse = sqrt(9+1) = sqrt(10)

    Cos theta is adj/hyp, and positive.

    Built, you're a mathmatician?

    Yeah, its just trig, its not too bad. Built answered everything already.

    Ew, I hate being a geek. I started to work it out without thinking. Thanks for giving the answers and relieving me from doing it on my own, Built.

    So, if I put questions about Linear Algebra up here next semester would you answer those too?

    Use a calculator. Thats what they are for.

    Seriously, if you are looking into a career that in anyway uses math, I would just bite the bullet and learn this stuff. Its soooo basic, that if you don't learn it now, when you get to the harder stuff, you'll never make it.

    its easy to say "just learn it" but i have little to no notes on this stuff. My teacher cant speak english. I can post a sound clip of him if you want me to (just need to know where i can host it)

    Are there any good sites for this type of math?
