y = sin(360) = sin(0) = 0
answer: y=0
You can use the graph by drawing a unit circle centered about the origin. Then find the point and the corresponding y value.
These angles are supplementary.
Complementary angles add up to 90 degrees. Supplementary angles add up to 180 degrees. 82 degrees + 98 degrees = 180 degrees.
If it’s asking how old was it when she bought it, it was two days old
if not then you gotta be more specific but i’m gladly able to help if you provide more info
if it’s asking how long it’s been exactly since she bought it then the answer is it has been 26 days
Cos^4(x) =
(cos²x)² =
(1-sen²x)² =
1² - 2*1*sen²x + sen^4x =
1 - 2sen²x + sen^4x
