Answer:
Answer in simplified form is:
(sinФ - cosФ)² + (sinФ + cosФ)² = 2
Step-by-step explanation:
Given,
(sinФ - cosФ)² + (sinФ + cosФ)²
This can be simplified as:
(sin²Ф + cos²Ф - 2sinФcosФ) + (sin²Ф + cos²Ф +2sinФcosФ)
We know that : sin²Ф + cos²Ф = 1
So,
( 1 - 2sinФcosФ) + (1 + 2sinФcosФ)
or 1 + 1 -2sinФcosФ + 2sinФcosФ
or 2
Hence we got (sinФ - cosФ)² + (sinФ + cosФ)² = 2
Answer:
Order pair (1,-1) satisfies x = y² only
Step-by-step explanation:
Given that
Equation graphed by Aaron = x = y²
Equation graphed by Jody = y = x²
Given that the coordinate pair (1,1) satisfies both the equations. lets check it for both equations one by one.
For equation (1)
1 = (1)²
1=1
For equation (2)
1 = (1)²
1=1
Now lets check both equations for ordered pair (1, -1)
For equation (1)
1 = (-1)²
1=1
For equation (2)
-1 = (1)²
-1=1 (False)
So this ordered pair satisfies the equation (1) only.
Omg I see this everywhere stop spamming
