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 does 2sin squared theta equal and why?

It is 2*sin(theta)*sin(theta) because that is how multiplication is defined!

Does cos squared x over sin squared x equal cot squared x?

Yes. Except where sin x = 0, because then you would be dividing by zero so the quotient is undefined.

What does cos squared x - Sin squared x equal?

2 x cosine squared x -1 which also equals cos (2x)

What is sine squared?

Answer 1 Put simply, sine squared is sinX x sinX. However, sine is a function, so the real question must be 'what is sinx squared' or 'what is sin squared x': 'Sin(x) squared' would be sin(x^2), i.e. the 'x' is squared before performing the function sin. 'Sin squared x' would be sin^2(x) i.e. sin squared times sin squared: sin(x) x sin(x). This can also be written as (sinx)^2 but means exactly the same. Answer 2 Sine squared is sin^2(x). If the power was placed like this sin(x)^2, then the X is what is being squared. If it's sin^2(x) it's telling you they want sin(x) times sin(x).

What is sin squared x minus cos squared x?

Sin squared, cos removed the x in the equation.

What is Cos squared x equal to?

Cos^2 x = 1 - sin^2 x

Does sin squared x plus cos squared x equal 1?

Yes. 'sin2x + cos2x = 1' is one of the most basic identities in trigonometry.

1 - 2cos2(x) and also 2sin2(x) - 1 Take your choice. Use whichever one is more convenient.

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

How do you prove that the sin over one minus the cosine minus one plus the cosine over the sine equals zero?

Multiply both sides by sin(1-cos) and you lose the denominators and get (sin squared) minus 1+cos times 1-cos. Then multiply out (i.e. expand) 1+cos times 1-cos, which will of course give the difference of two squares: 1 - (cos squared). (because the cross terms cancel out.) (This is diff of 2 squares because 1 is the square of 1.) And so you get (sin squared) - (1 - (cos squared)) = (sin squared) + (cos squared) - 1. Then from basic trig we know that (sin squared) + (cos squared) = 1, so this is 0.

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

Is all sin equal?

yeah. a sin is still a sin.
