A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

What does negative sine squared plus cosine squared equal?

To determine what negative sine squared plus cosine squared is equal to, start with the primary trigonometric identity, which is based on the pythagorean theorem...sin2(theta) + cos2(theta) = 1... and then solve for the question...cos2(theta) = 1 - sin2(theta)2 cos2(theta) = 1 - sin2(theta) + cos2(theta)2 cos2(theta) - 1 = - sin2(theta) + cos2(theta)


What does 1 minus cosine theta equal?

There is no easy simplification.


Do the equations sine plus cosine and sine squared plus cosine squared both equal 1?

No, they do not.


What is cosine 2 theta when sine theta equals .28?

If sine theta is 0.28, then theta is 16.26 degrees. Cosine 2 theta, then, is 0.8432


What does 2sin squared theta equal and why?

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


What is Theta multiplied by cosine Theta?

It is a non-linear function of theta.


What are the values of theta of which secant theta is undefined?

Since secant theta is the same as 1 / cosine theta, the answer is any values for which cosine theta is zero, for example, pi/2.


Is cos theta is equal to 1?

No, not necessarily. Cosine theta is equal to 1 only when theta is equal to zero and multiples of 2 pi radians or multiples of 360 degrees. This is because cosine theta is hypotenuse over adjacent, and the ratio 1 only occurs at 0, 360, 720, etc. or 0, 2 pi, 4 pi, etc.
