Question

Solve the equations below exactly Give your answers in radians, and find all possible values for t If there is more than one answer, enter your solutions in a comma separated list
(a) sin(t)= sqroot(2)/2 when t=
(b) cos(t)=1/2 when t=
(c) tan(t)=-1 when t=

Answer 1

Review your standard angles:

0, π/6, π/4, π/3, π/2
and signs in the quadrants

Then solving these will be a cinch.
