Question

what is the differnence between 1+sin²A and ( 1+ sin A )²​

Answer 1

Answer:

If you are just asking how the two are different, then:

1 + sin²A = 1 + (sinA)²

But,

(1 + sinA)² = 1² + 2sinA + sin²A

If you are literally asking the difference, then:

(1 + sinA)² - (1 + sin²A) = 1² + 2sinA + sin²A - 1 - sin²A

= 2sinA
