This is the composite transorfmation that I have

enter image description here

this is the working that I did, but something tells me this might not be the right answer, enter image description here P.S can some with more points add composite transformation tag? tks

This is the formula that i have so hence the working below enter image description here

    What are $q_a$ and $r_c$?2012-10-17

    @copper.hat Its not given just the a and b not $q_a$, i think there is a formula to show this..2012-10-17

    @copper.hat u c that I have added a screen shot of the formula2012-10-17

    I have no idea what this question is asking. We need to know what $q_a$ is.2012-10-17

    @wj32 but there is no such as $q_a$ take a look at my new picture2012-10-17

    Judging by the composition rules, I'm guessing that $q_a$ is a reflection about a line of angle $a$ and $r_b$ is a rotation by an angle $b$. To solve this, we would need not just the composition rules in the picture, but also the fact that $r_{\theta}=r_{\theta+2\pi k}$.2012-10-17

    @Aaron yes aaron that is true but also I am sure you are aware of the composition rules.2012-10-17

    Yes, but I wouldn't have known the composition rules (without the picture of them) unless I already knew what the transforms were. This is why everybody was asking. When you ask a question, it is important to remember that not everybody has the same context as you. It is important to say what things mean unless you are certain your notation and terms are completely standard and universally used. If you had said "rotation and reflection" you would have had an answer 8 hours sooner.2012-10-17

    @Aaron oops lesson learnt! tks buddy2012-10-17

Your answer should be $r_{-3.4+2\pi}$ since you are working with radians, not degrees.

    That seems logical. tks2012-10-17
