Hey! I'm sorry if I put this post in the wrong place, however, I need help. And please move it if it was placed wrongly. So basically I'm a sixteen year old boy which have slacked in math since 8th grade. And now that I'm a High school student starting my second year I've understood the seriousness of the situation I'm in, as I barely passed last semester I'm not sure if I will pass the next one, even though it is the easiest level of math in the second year. I've finally decided to shape up my math. I am proficient in all of the basic maths of course like multiplication, division and stuff like that. However I'm almost completely blank in Algebra, and that is the pillar of what I'm learning next year, or in a month! So it is possible for me to get my Algebra up and running in a month, now I don't even know how wide the subject spans! I do know that Algebra is a precursor to Trigonometry. Anyways, I bought 2 books on algebra and I'm planning on sitting the next 30 days studying. So I guess my question is, is it doable? And what else do I need to learn to pass the math course? Thank you for all answers, helpful or not.  Barelyable

All I can say is study hard, and you can achieve it.

Yes there will be trigonometry. And I'll admit that I've paid close to zero attention to math classes and almost embarrassed to mention that I don't know what trigonometry, sin, cos, tan is.

Also I've purchased two books, don't know if they're any good, algebra for dummies one and two, hehe

I can give the definition for you, though. Suppose you have a right triangle, that is, a triangle with one right angle (90 degrees). Pick one of the other angles; the sine of that angle is the length of the opposite side divided by the length of the hypotenuse (the longest side, the one opposite the right angle). The cosine is the length of the adjacent leg divided by the length of the hypotenuse. The tangent is the length of the opposite leg divided by the length of the adjacent leg. This would be clearer with a picture; look at http://neaportal.k12.ar.us/wpcontent/u ... angent.jpg for example.
