What is (sin(x))^2 and (cos(x))^2

[From: ] [author: ] [Date: 11-07-09] [Hit: ]
......
Sin[x]^2


=

1/2 (1 - Cos[2 x])


------------------------


Cos[x]^2

1/2 (1 + Cos[2 x])

-
1

(sin(x))^2 + (cos(x))^2 = 1

(i'm taking and as plus, like when people say what is one and one, they mean one plus one)

-
sin and cos are on your calculator x is the angle and the up arrow and 2 is to the power of 2

-
it is mostly used in algebra 2 to figure out what sine,cosine,or tangent is.

-
it is just sin^2x and cos^x
