please help me with the question: sin x=1 - cos x
-------------------------------------------------
Hey, this is not a question. It is an equation.
If you want to solve it, say "Please help me solve this equation".
OK, let's solve it.
sin(x) = 1 - cos(x).
In the left side, replace sin(x) = to get the equation for one uniform unknown cos(x):
= , ---> square both sides --->
= ,
= ,
. = ,
a) cos(x) = 0 -----> x = , k = 0, +/-1, +/-2, . . .
b) cos(x) = 1 -----> x = , k = 0, +/-1, +/-2, . . .
