sin^2(x)cos^2(x)=(2-sqrt(2))/(16)

Solution

sin^{2} (x) cos^{2} (x) = \frac{2 - 2}{16}

Solution

x = 0.19634 \dots + 2 πn, x = π - 0.19634 \dots + 2 πn, x = - 0.19634 \dots + 2 πn, x = π + 0.19634 \dots + 2 πn, x = 1.37444 \dots + 2 πn, x = π - 1.37444 \dots + 2 πn, x = - 1.37444 \dots + 2 πn, x = π + 1.37444 \dots + 2 πn

Degrees

x = 11.2 5^{\circ} + 36 0^{\circ} n, x = 168.7 5^{\circ} + 36 0^{\circ} n, x = - 11.2 5^{\circ} + 36 0^{\circ} n, x = 191.2 5^{\circ} + 36 0^{\circ} n, x = 78.7 5^{\circ} + 36 0^{\circ} n, x = 101.2 5^{\circ} + 36 0^{\circ} n, x = - 78.7 5^{\circ} + 36 0^{\circ} n, x = 258.7 5^{\circ} + 36 0^{\circ} n

Solution steps

sin^{2} (x) cos^{2} (x) = \frac{2 - 2}{16}

Subtract

\frac{2 - 2}{16}

from both sides

sin^{2} (x) cos^{2} (x) - \frac{2 - 1}{8 2} = 0

Simplify

sin^{2} (x) cos^{2} (x) - \frac{2 - 1}{8 2} : \frac{8 2 sin ^{2} ( x ) cos ^{2} ( x ) - 2 + 1}{8 2}

sin^{2} (x) cos^{2} (x) - \frac{2 - 1}{8 2}

Convert element to fraction:

sin^{2} (x) cos^{2} (x) = \frac{sin ^{2} ( x ) cos ^{2} ( x ) 8 2}{8 2}

= \frac{sin ^{2} ( x ) cos ^{2} ( x ) \cdot 8 2}{8 2} - \frac{2 - 1}{8 2}

Since the denominators are equal, combine the fractions:

\frac{a}{c} \pm \frac{b}{c} = \frac{a \pm b}{c}

= \frac{sin ^{2} ( x ) cos ^{2} ( x ) \cdot 8 2 - ( 2 - 1 )}{8 2}

Expand

sin^{2} (x) cos^{2} (x) \cdot 82 - (2 - 1) : sin^{2} (x) cos^{2} (x) \cdot 82 - 2 + 1

sin^{2} (x) cos^{2} (x) \cdot 82 - (2 - 1)

= 82 sin^{2} (x) cos^{2} (x) - (2 - 1)

- (2 - 1) : - 2 + 1

- (2 - 1)

Distribute parentheses

= - (2) - (- 1)

Apply minus-plus rules

- (- a) = a, - (a) = - a

= - 2 + 1

= sin^{2} (x) cos^{2} (x) \cdot 82 - 2 + 1

= \frac{8 2 sin ^{2} ( x ) cos ^{2} ( x ) - 2 + 1}{8 2}

\frac{8 2 sin ^{2} ( x ) cos ^{2} ( x ) - 2 + 1}{8 2} = 0

\frac{f ( x )}{g ( x )} = 0 \Rightarrow f (x) = 0

82 sin^{2} (x) cos^{2} (x) - 2 + 1 = 0

Rewrite using trig identities

1 - 2 + 8 cos^{2} (x) sin^{2} (x) 2

Use the Pythagorean identity:

cos^{2} (x) + sin^{2} (x) = 1

cos^{2} (x) = 1 - sin^{2} (x)

= 1 - 2 + 8 (1 - sin^{2} (x)) sin^{2} (x) 2

1 - 2 + (1 - sin^{2} (x)) \cdot 8 sin^{2} (x) 2 = 0

Solve by substitution

1 - 2 + (1 - sin^{2} (x)) \cdot 8 sin^{2} (x) 2 = 0

Let:

sin (x) = u

1 - 2 + (1 - u^{2}) \cdot 8 u^{2} 2 = 0

1 - 2 + (1 - u^{2}) \cdot 8 u^{2} 2 = 0 : u = \frac{2 - 2 64 + 32 2 + 16}{8}, u = - \frac{2 - 2 64 + 32 2 + 16}{8}, u = \frac{2 2 64 + 32 2 + 16}{8}, u = - \frac{2 2 64 + 32 2 + 16}{8}

1 - 2 + (1 - u^{2}) \cdot 8 u^{2} 2 = 0

Expand

1 - 2 + (1 - u^{2}) \cdot 8 u^{2} 2 : 1 - 2 + 82 u^{2} - 82 u^{4}

1 - 2 + (1 - u^{2}) \cdot 8 u^{2} 2

= 1 - 2 + 82 u^{2} (1 - u^{2})

Expand

8 u^{2} 2 (1 - u^{2}) : 82 u^{2} - 82 u^{4}

8 u^{2} 2 (1 - u^{2})

Apply the distributive law:

a (b - c) = ab - a c

a = 8 u^{2} 2, b = 1, c = u^{2}

= 8 u^{2} 2 \cdot 1 - 8 u^{2} 2 u^{2}

= 8 \cdot 1 \cdot 2 u^{2} - 82 u^{2} u^{2}

Simplify

8 \cdot 1 \cdot 2 u^{2} - 82 u^{2} u^{2} : 82 u^{2} - 82 u^{4}

8 \cdot 1 \cdot 2 u^{2} - 82 u^{2} u^{2}

Apply exponent rule:

a^{b} \cdot a^{c} = a^{b + c}

= 82 u^{2 + 2}

Add the numbers:

2 + 2 = 4

= 82 u^{4}

= 82 u^{2} - 82 u^{4}

= 82 u^{2} - 82 u^{4}

= 1 - 2 + 82 u^{2} - 82 u^{4}

1 - 2 + 82 u^{2} - 82 u^{4} = 0

Write in the standard form

a_{n} x^{n} + \dots + a_{1} x + a_{0} = 0

- 82 u^{4} + 82 u^{2} + 1 - 2 = 0

Rewrite the equation with

v = u^{2}

and

v^{2} = u^{4}

- 82 v^{2} + 82 v + 1 - 2 = 0

Solve

- 82 v^{2} + 82 v + 1 - 2 = 0

Solve with the quadratic formula

- 82 v^{2} + 82 v + 1 - 2 = 0

= 2 \cdot 2 \cdot 2 \cdot 4

4

divides by

24 = 2 \cdot 2

= 2 \cdot 2 \cdot 2 \cdot 2 \cdot 2

2

is a prime number, therefore no further factorization is possible

= 2 \cdot 2 \cdot 2 \cdot 2 \cdot 2

= 2^{5}

= 2^{5}

Apply exponent rule:

a^{b + c} = a^{b} \cdot a^{c}

= 2^{4} \cdot 2

Apply radical rule:

= 2 2^{4}

Apply radical rule:

2^{4} = 2^{\frac{4}{2}} = 2^{2}

= 2^{2} 2
