sin^2 A + cos^2 A = 1

Dividing by cos^2 A we get:
sin^2 A / cos^2 A + cos^2 A / cos^2 A = 1 / cos^2 A
tan^2 A + 1 = sec^2 A this is Option B and Option D.

What is 2xy-3yz+5+2yz-xy

melomori [17]

To simplify this expression, we are going to combine like terms.

First, we can see that we have two terms with the variables $xy$ being multiplied together, $2xy$ and $-xy$ . Together, these add to $xy$ , so our expression is now:

$xy - 3yz + 5 + 2yz$

We also have two terms with $yz$ , $-3yz$ and $2yz$ . Together, these add to $-yz$ , so our expression is now:

$xy - yz + 5$

Our final expression is xy - yz + 5.
