What else can I help you with?
Law of cosines with a right angle?
The law of cosines with a right angle is just the pythagorean theorem. The cosine of 90 degrees is 0. That is why the hypotenuse squared is equal to the sum of both of the legs squared
What is the value of the angle in which the sine and cosine are equal and both negative?
225 degrees
How many solutions can two unique equations that both have two squared variables?
Four.
Do linear equations contain x squared?
No, linear equations don't have x2. Equation with x and y are usually linear equations. Equations with either x2 or y2 (but never both) are usually quadratic equations.
If you are asked to solve a system of equations in which there is no linear equation to start with you can sometimes begin by isolating and substituting a variable that is squared in both equations.?

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
Up to how many solutions can there be in a system of two unique equations that both have two squared variables?
4
Is tan squared x equal tan x squared?
Yes. Both expressions are the same.
Why do so many physics equations have variables squared?
Many physics equations involve variables squared because it represents a relationship between two quantities that involves both of them multiplied by each other. Squaring a variable allows for the representation of non-linear relationships and calculations involving quantities that are squared, such as areas or volumes.
