Udacity College Algebra Question

  1. Jul 3, 2013 #1
    I'm going to be a sophomore in high school this coming school year and I want to major in physics and/or mathematics in college so I am doing the college algebra course from Udacity to further my education. I am wondering; after taking this course will I have all I need to be able to move on to trigonometry or will I still need to focus more on algebra? If I can move on what are some good online trigonometry courses? If I shouldn't move on what else should I learn and where should I learn it from? I know this is a lot of questions but I have been wondering this for a while and any help would be appreciated. Thanks.

    Here is what the course covers:

    Lesson 1: Number
    Lesson 2: Expressions
    Lesson 3: Polynomials
    Lesson 4: Equations
    Lesson 5-1: Coordinates
    Lesson 5-2: Distance
    Lesson 5-3: Midpoints And Slope
    Lesson 6-1: Slope And Equations
    Lesson 6-2: Points
    Lesson 7: Forms of the Equation of a Line
    Lesson 8: Inequalities And Absolute Value
    Lesson 9: More Inequalities And Equations
    Lesson 10: Parabolas
    Lesson 11: Factoring
    Lesson 12: Quadratic and Rational Inequalities
    Lesson 13: More Parabolas
    Lesson 14: Completing the Square
    Lesson 15: Quadratic Formula
    Lesson 16: Complex Numbers
    Lesson 17: Functions
    Lesson 18: Domain and Range
    Lesson 19: Behavior of Functions
    Lesson 20: Factor Theorem
    Lesson 21: Rational Zero Test
    Lesson 22: Intermediate Value Theorem
    Lesson 24: Asymptotes
    Lesson 25: Slant Asymptotes
    Lesson 26: Transformations
    Lesson 29: Exponential Functions
    Lesson 30: Scientific Notation
    Lesson 31: Logarithmic Functions
    Lesson 32: Log Properties
    Lesson 33: Solving Exponential and Logarithmic Equations
    Lesson 34: Population, Scrolls and Sound

    This may cover most of Algebra 2 but I am wondering if there is enough practice problems for this course to be sufficient enough for me to be able to move on to trigonometry immediately after I finish the course.

    This looks like a comprehensive course. For sure you won't need anything else to learn trigonometry. I suggest you learn chapters 1-15, then trigonometry, then 16-34. I see learnerstv.com has some trig videos, have a look there.

    You'll be very well set in algebra. Definitely find something for trigonometry, or if you can find a "precalculus" class you will review some algebra (always good) as well as get the trigonometry you use.

    It doesn't seem Udacity has either right now, but maybe they will offer it. I checked coursera, and they only have one in Spanish right now. (Come to think of it, I could *really* brush up on my spanish if I took it....)

    So, I would advice good old khanacademy.org for all your math needs: https://www.khanacademy.org/math/trigonometry
