      tanx = sinx cosx and cotx = cosx sinx. Notice that tanx = 1/cotx, so these two functions are reciprocal functions. Exercise. For what values of x is tanx undefined? For what values of x is cotx undefined? [Hint: Check when the denominator is zero.] We can interpret tanx on the unit circle. The function tanx can be measured by using the ...

      cosx = 0, and cotx and cscx are undefined whenever sinx = 0. By definition, cosx and sinx are the coordinates of the point on the unit circle (i.e., the circle of radius one centered at the origin) x radians counterclockwise from the positive horizontal axis. slope = tanx (cosx,sinx) 1 x radians sinx cosx 1 x Consequently, the ray through the ...

      Periodicity: sinx, cosx have period 2π; tanx, cotx have period π Symmetry: cos is an even function, sin,tan,cot are odd. Turning sin to cos: sin(π 2 −x) = cosx cos(π 2 −x) = sinx Relating tan and sec: 1+tan2 x = sec2 x , 1+cot2 x = csc2 x Expanding sums: sin(x±y) = sinxcosy ±cosxsiny , cos(x±y) = cosxcosy ∓sinxsiny Products to sums ...
