Verificar si las siguientes igualdades son identidades trigonométricas:
❶ ^2 = 1 + ^2
❷ ^2 . 2 . 2 = 1
❸ (1 − ^2 ) (1 + ^2 ) =
❹ ( + )^2 / . = 2 + .
❺ ( + )^2 / . . . =2 . .
❻ [1+ / ] [1+ / ] / √1−^2 = .
❼ + + ^2 / . − = . + .
❽ ^2 + / [ 1/2 − 1 / ^2 −1] = 1
❾ ^2 - 1 / 1 + ^2 +sec2 /^2 . ^2 = ^2 − 1/2​
