Given that sinx = 1/2, cos x = (rt.3)/2 and 0 degrees less than or equal x less than or equal 360 degrees,
a) Find the values of x
b) write down the exact value of tan x.
My solution is...
a) x = 30, 150, 330
but the book only says that 30 degrees is the solution... am I right? or is the book right?
b) I have two exact values for tanx: 1/(rt.3) and -1/(rt.3)
but the book has it down as: (rt.3)/3
Are my answers correct?
