because only at
at and
similar argument for when they both equal -1.
solve for "theta" to the nearest degree,0degrees ≤ "theta" ≤ 360degrees.
A. SIN2 "Theta" = 1
B. Tan2 "Theta" = 1
My question is that why does question A. only belong to TWO quadrants, while question B belong FOUR quadrants.
Please provide explanation
-Thanks again
