    The video will automatically pause when it reaches a problem.

    tan function

    SL 3.7

    Since tanx=cosxsinx​, y=tanx will have vertical asymptotes whenever cosx=0 (eg 2π​,23π​…). And since

    tan(x+π)=cos(x+π)sin(x+π)​=−cosx−sinx​=tanx

    the period of tanx is π.


    The domain is thus x=22k+1​π, and the range is all real numbers R.
