Let cosa be the fourth power of sin times a-SiN's Square times a + cos's Square times a

Let cosa be the fourth power of sin times a-SiN's Square times a + cos's Square times a

(sinA)^4-(sinA)^2+(cosA)^2
=[1-(cosA)^2]^2+2(cosA)^2-1
Expand, simplify
We get (COSA) ^ 4, which is the fourth power of cosa

Using cosa to express SiN4 power a-sin2 power a + Cos2 power a

The original formula = sin? A (sin? 2a-1) + cos? A
sin²a(-cos²a)+cos²a
=cos²a(1-sin²a)
=cos²a*cos²a
=(cosa)^4

Given cos square a + cosa-1 = 0, find the value of sin square a + sin 6 power a + sin 8 power a

From cos squared a + cosa-1 = 0
cosa=1-cos^a=sin^2a
That is sin ^ 2A = cosa
Replace sin square a + sin 6 power a + sin 8 power a
=cosa+cos^3a+cos^4a
Substituting cos ^ 2A = 1-cosa into
The original formula = cosa + cosa (1-cosa) + (1-cosa) ^ 2
=2cosa-cos^2a+1-2cosa+cos^2a
=1

Cos square α (sin square α - 1) + cos square α = cos quartic α?

Left = cos square a (sin square a sin square a cos square a) + cos square a
=-Cos quartic a + cos square a
=Cos square a (1-cos square a)
=Cos square asin square a

How many powers of 2 equals 10000

log2(10000)

If we know that the fourth power of the unknown number is equal to 3, and the B power of the unknown number is equal to 5, what is the 3a-2b power of the unknown number?

The a power of the unknown is equal to 3. Find the unknown number to the power of 3a-2b
The information of the original question can be extracted as x ^ a = 3, x ^ B = 5 (^ is the power)
According to the rule of square calculation formula, x ^ (3a-2b) = x ^ 3A / x ^ 2B = (x ^ a) ^ 3 / (x ^ b) ^ 2 = 3 ^ 3 / 5 ^ 2 = 27 / 25
