Answer:
It's false.... correct is a2+2ab+b2
Step-by-step explanation:
This cannot be factored anymore although. when we try to substitute a with 5 and b with 2, the answer in the right hand side of the equation is -9.
That's why it's false.
Step-by-step explanation:
sec(x) = 1/cos(x)
cot(x) = cos(x)/sin(x)
sec is smaller than cot, if cos is negative (making sec negative) and sin is negative (making cot positive).
and that is true for the third quadrant.
which is pi < x < 3×pi/2
so, the third answer is right.
Looking at the table everything is correct if that is what you are asking.
