Question 925789: Solve the given equation: sin t − 1 = cos t?

I have to find an identity that will allow me to convert the given equation to an equation involving just sin or just cos. Since sin^2 t and cos^2 t are linked in an identity, I need to square both sides of the equation to obtain
sin^2 t +____= cos^2 t
Substitute ____ for cos^2 t. This gives us the equation
sin2 t +____ =
Please help

sin%5E2%28t%29-2sin%28t%29%2B1=cos%5E2%28t%29 when both sides squared.

sin%5E2%28t%29-2sin%28t%29%2B1=1-sin%5E2%28t%29

2sin%5E2%28t%29-2sin%28t%29=0

highlight%28sin%5E2%28t%29-sin%28t%29=0%29
