Hello friend

Good morning

Your answer is given below you can check :

 = > { \sin(a) }^{2} \: { \cos(b) }^{2} - { \cos(a) }^{2} { \sin(b) }^{2} \\ \\ = > it \: is \: the \: identity \\ \\ so \: = > {\cos}^{2}\:(a + b)

I hope it will help you

Answer: sin²A-sin²B


Step-by-step explanation:

given that

sin²A cos²B - cos²A sin²B

=sin²A(1-sin²B)- [(1-sin²A)sin²B]

=sin²A-sin²A sin²B-[sin²B- sin²A sin²B]

=sin²A-sin²A sin²B-sin²B+ sin²A sin²B

=sin²A-sin²B
