What is sin squared x minus cos squared x?
Sin squared, cos squared...you removed the x in the equation.
What does cos squared x - Sin squared x equal?
2 x cosine squared x -1 which also equals cos (2x)
How do you factor sin squared times x plus cos2x -cosx equals 0?

What is the integral of sec squared x?
tan(x) + C d/dx tan(x) = d/dx (sin(x))/(cos(x)) = (sin^2(x)+cos^2(x))/(cos^2(x)) = 1/(cos^2(x)) = sec^2(x) NEVER FORGET THE CONSTANT!
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
How do you differentiate sin squared x plus cos squared x?
The deriviative of sin2 x + cos2 x is 2 cos x - 2 sin x
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 minus cos squared x?
Sin squared, cos squared...you removed the x in the equation.
What is Sin squared x - Cos squared x divided by 1 - Tan squared x equals cos squared x?

What does cos squared x - Sin squared x equal?
2 x cosine squared x -1 which also equals cos (2x)
Differentiate cos x with respect to x?
d/dx(cos x) = -sinx
What is Cos squared x equal to?
Cos^2 x = 1 - sin^2 x
Differentiate sin x with respect to x?
y = Sin(x) dy/dx = Cos(x)
Is 1- cos 2 x 1 plus cos 2 x equals sin squared x cos squared x an identity?
No, (sinx)^2 + (cosx)^2=1 is though
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 equals 1 cos squared x divided by cos squared x?
1. Anything divided by itself always equals 1.
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)
