The tan is a lot easier since its easy to calculate or solve all together
a) sin (pi + pi/6)
What I did so far,
sin (a+b) = sinacosb + cosasinb
sin (pi + pi/6) = sin pi cos pi/6 + cos pi sin pi/6
                               =0      =√3/2        =-1       =1/2     
b) sin (pi + x)
c) cos(x + pi/2)
d) tan (2pi - x) <- this one was a little weird
