1. The range for x, -pi/2 <= x <=0, restricts x to the 4th quadrant.

What angle x in the 4th quadrant has the property that cos(x) = sqrt(3)/2?

verify for sqrt(1-cosx)= sin/sqrt(1+cosx). I multiplied the right side by sqrt(1-cosx) and got sqrt(1-cosx)= sin*sqrt(1-cosx), but I don't know what to do with the sin.

For f(x) = 2sinx + (sinx)^3 + tanx find f'(pi/3). Ok, so what I tried was... f'(x) = 2cosx + cosx(3(sinx)^2) + (sinx/cosx) pi/3 = (1/2, sqrt(3)/2) therefore, 2(1/2) + 1/2(3(sqrt(3)/2)(sqrt(3)/2) + (sqrt(3)/2 (2/1)) 1 + .5(3 (3/4))
