it equals positive one. one squared is always one. if they're both negative, negative times negative is always positive.
Cosine squared theta = 1 + Sine squared theta
The two numbers in question are 1 and 9. 1 is equal to 1 squared, and 9 is equal to 3 squared.
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
Yes. 'sin2x + cos2x = 1' is one of the most basic identities in trigonometry.
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.
Sin squared is equal to 1 - cos squared.
(1 metre) squared = (1000 mm) squared = 1000000 mm squared.
Neither, one liter is equal to 1 decimeter cubed.
one squared equals one.
1. 1x1=1
There is no such thing as 1 SQUARED by 5. It is actually 1 to the 5th power, which is 1.
No
No, it equals 0. If you have nothing, and you multiply it by nothing, you still have nothing.
Cosine squared theta = 1 + Sine squared theta
1 squared plus 8 squared or 4 squared plus 7 squared
1 squared radical 40 is equal to 1 squared radical (4 x 10), and this become 2 squared radical 10. By adding 2 squared radical10 with 3 squared radical 10 we get 5 squared radical 10.
i = sqrt of (-1) ( imaginary) i squared = sqrt(-1) x sqrt (-1) = -1 (minus one)
