If sinθ = -2/3, which of the following are possible?
*check all that apply*

a) secθ= -3/2 & tanθ = 2/√5
b) secθ = 3/√5 & tanθ = -2/√5
c) cosθ = √5/3 & tanθ = 2/√5
d) cosθ = -√5/3 & tanθ = 2/√5

i think it is b & c but i am not sure.

question: the type of image formed by a convex lens is determined by the objects?

answer: it depends on the shape of the lens and the position of the object.

explanation: because if it was not positioned correctly it would have a diffrent image of what you were expecting to see
