find angle theta that corresponds to the function

Question

Use the unit circle, reflection, and symmetry to determine the angle θ that corresponds to the given function value in the given quadrant. If no such angle exists, write DNE. (As always, give exact values.)

sin⁡(θ)=sqrt2/2 and θ is in quadrant two: θ= 

csc⁡(θ)=2 and θ is in quadrant one: θ= 

cos⁡(θ)=−1/2 and θ is in quadrant two: θ= 

tan⁡(θ)=sqrt3 and θ is in quadrant three: θ=
