    Exercises with Conversion

    Hello. I am making a research about representations in trigonometry. I am trying to find exercises with conversions from one representation to other. The 5 type of trigonometric representation i will use are trigonometric functions, right triangle, trigonometric circle, trigonometric identities, trigonometrics graphs. For example, "Sketch y=sinx" is a conversion from trigonometric function to trigonometrics graphs. Any ideas?

    Re: Exercises with Conversion

    Hey Xaris.

    For trigonmetric identities you might want to look at Eulers Identity In Complex Numbers where e^(iax) = cos(ax) + isin(ax) = [e^(ix)]^a. This is used to show a lot of identities.

    In terms of functions, just note that sin(x+2pi) = sin(x) and cos(x+2pi) = cos(x) with tan(x+pi) = tan(x) and also use the fact that e^(ix) = cos(x) + isin(x).

    Right angled triangles can be used to find formulas for things like arcsin(cos(x)) and arccos(sin(x)) and things involving compositions of inverse trig with trig functions.

    The right angle is just a special case of the circle geometrically.

    Those should give you somewhere to start.
