Is trigonometry required for calculus

  1. Feb 3, 2012 #1
    Hello, I've recently been reading "Calculus made Easy" and realized that I've completely skipped over learning trigonometry. After the class I was taking (seventh grade advanced math, sadly) became completely insufficient for my desire to learn. I picked up the book at the local library, unfortunately forgetting about trigonometry until I ran into sine and cosine references. So I was wondering if knowing trigonometry is required for calculus or if I should just get the basic grasp on it.

    It's helpful to have a basic sense of what the sine and cosine represent. Most of trigonometry isn't used for calculus, though.

    For better or worse if you are going to anything with calculus, it is hard to avoid trigonometry.

    Never mind what I said earlier. This guy's right.

    You'll need to know about sines, cosines, tangents, etc. You'll absolutely need to know about identities with those things. Identities like [itex]\cos^2(x)+\sin^2(x)=1[/itex] or [itex]2\cos(x)\sin(x)=\sin(2x)[/itex] are important.

    Less important are the triangle-thingies. Formulas like sohcahtoa or the cosine rule are not so prevalent.
