Answer:
u good? lol ?
Step-by-step explanation:
what is your question though. if its create an equation, its
y = 1/6x + 2
see explanation
Using the trigonometric identity
sin²x + cos²x = 1
Consider the left side
2cos²A - 1 ← replace 1 by sin²A + cos²A
= 2cos²A - ( sin²A + cos²A)
= 2cos²A - sin²A - cos²A
= cos²A - sin²A = right side ⇒ verified
