Question

Solve the equation for t. (Use the parameter k as necessary to represent any integer).

1) sin(t) = −(1/2)

2) cos(t) = -( (SQUARE ROOT 2)/ 2)

Answer 1

sin x=sin y means

\[\large x=n \pi \pm (-1)^n(y)\]

Answer 2

so first find a y value for x=-1/2 then substitute in the equation for y
