How many true solutions does the equation sinx=cosx-1 have over the interval 0 is less than or equal to x which is less than or

FrozenT [24]

$sinx=cosx-1 \\ \\ 
sinx-cosx=-1$

Using the identity: $sinx-cosx=- \sqrt{2}cos( \frac{ \pi }{4}+x)$ , we get:

$- \sqrt{2}cos( \frac{ \pi }{4}+x)=-1 \\ \\ 
cos( \frac{ \pi }{4}+x)= \frac{1}{ \sqrt{2} } \\ \\ 
$

There are two solutions to this equation:

1)
$\frac{ \pi }{4}+x= \frac{ \pi }{4} \\ \\ 
x=0$

Since the period of cosine is 2π, so 0 + 2π = 2π will also be a solution to the given equation

2)
$\frac{ \pi }{4}+x= \frac{7 \pi }{4} \\ \\ 
x= \frac{3 \pi }{2}$

Therefore, there are 3 solutions to the given trigonometric equation.
