Step-by-step explanation:
sin²a + cos²a + sec²a - tan²a
sin²a + cos²a = 1
1 + tan²a = sec²a
So, sec²a - tan²a = 1
sin²a + cos²a + sec²a - tan²a
= 1 + 1 = 2
The nail will stick to the magnet because it will become magnetized.Also because the north pole in the magnet rearranges the magnet domains inside the steel so that their south poles all point toward the north pole of the permanent magnet
