Answer 1

theta =0

Answer 2

no it's not

Answer 3

more generally it's solved at -pi/2 * 2pi k and 2pi * k for all k

Answer 4

i mean -pi/2 + 2pi k and 2pi k

Answer 5

where do you get sin(t) = cos(t)? the original equation was sin(t)-cos(t)=1

Answer 6

i mean cos(t)-sin(t)=1

Answer 7

right i misread the question

Answer 8

I double checked. I was told they were identities but I just had the person who told me that they were identites check and yes I stand corrected. They are equations.

Answer 9
