What does cos squared x - Sin squared x equal?
2 x cosine squared x -1 which also equals cos (2x)
What does Sin squared x - Cos squared x equal?
1 - 2cos2(x) and also 2sin2(x) - 1 Take your choice. Use whichever one is more convenient.
What is sin squared x minus cos squared x?
Sin squared, cos squared...you removed the x in the equation.
How do you factor sin squared times x plus cos2x -cosx equals 0?

How do you show that 2 sin squared x minus 1 divided by sin x minus cos x equals sin x plus cos x?
(2 sin^2 x - 1)/(sin x - cos x) = sin x + cos x (sin^2 x + sin^2 x - 1)/(sin x - cos x) =? sin x + cos x [sin^2 x - (1 - sin^2 x)]/(sin x - cos x) =? sin x + cos x (sin^2 x - cos^2 x)/(sin x - cos x) =? sin x + cos x [(sin x - cos x)(sin x + cos x)]/(sin x - cos x) =? sin x + cos x sin x + cos x = sin x + cos x
What does cos squared x - Sin squared x equal?
2 x cosine squared x -1 which also equals cos (2x)
What does Sin squared x Cos squared x equal?
sin2 x = (1/2)(1 - cos 2x) cos2 x = (1/2)(1 + cos 2x) Multiplying both you get (1/4) (1 - cos2 2x) Which is equal to (1/4) (1 - (1/2) (1 + cos 4x) = (1/8) (2 - 1 - cos 4x) = (1/8) (1 - cos 4x) Or If it is the trigonomic function, sin squared x and cosine squared x is equal to one
What is Cos squared x equal to?
Cos^2 x = 1 - sin^2 x
What does 1 - cos squared equal?
Note that an angle should always be specified - for example, 1 - cos square x. Due to the Pythagorean formula, this can be simplified as sin square x. Note that sin square x is a shortcut of (sin x) squared.
What is cos squared x equal?
1 - sin2x(1+ cos2x)/2
Is cos squared x the same as cos x squared?
No. Cos squared x is not the same as cos x squared. Cos squared x means cos (x) times cos (x) Cos x squared means cos (x squared)
What is Sin squared x - Cos squared x divided by 1 - Tan squared x equals cos squared x?
22
How many solutions does cos squared minus two cos equal three?
One solution. (cos x)2 - 2cos x = 3 Factor: (cos x - 3)(cos x + 1)= 0 cos x = {-1, 3} Solve: For cos x = -1, x = 180 deg No solution for cos x = 3
Does sin squared x plus cos squared x equal 1?
Yes. 'sin2x + cos2x = 1' is one of the most basic identities in trigonometry.
What is (1 plus cos x)(1- cos x)?
(1+cosx)(1-cosx)= 1 +cosx - cosx -cos^2x (where ^2 means squared) = 1-cos^2x = sin^2x (sin squared x)
What does Sin squared x - Cos squared x equal?
1 - 2cos2(x) and also 2sin2(x) - 1 Take your choice. Use whichever one is more convenient.
What is (1 cos x)(1- cos x)?
(1+cosx)(1-cosx)= 1 +cosx - cosx -cos^2x (where ^2 means squared) = 1-cos^2x = sin^2x (sin squared x)
