trigonometry
Hi eveybody,
I have a TI-89.I would like to solve this trigonometric
equation: sin((pi/4)-2x)-sin(x)=0.
I would like to know the EXACT results but the TI-89 will give
me the approximate results only.Can anyone tell me why?
Can't I optain the exact solutions for this
equation.
I have also found that the TI-89 is not very strong in trigo
functions.For example you cannot optain a trigo expression
with tan,sin,cos or what you want.
Thank you a lot for help.
