Integrate sin²2x cos²2xdx

Masteriza [31]

$\sin^2x=\dfrac{1-\cos2x}2$
$\cos^2x=\dfrac{1+\cos2x}2$

From the identities above, you have

$\sin^22x\cos^22x=\dfrac{(1-\cos4x)(1+\cos4x)}4=\dfrac{1-\cos^24x}4$

Applying once more, you have

$\dfrac{1-\cos^24x}4=\dfrac{1-\dfrac{1+\cos8x}2}4=\dfrac{1-\cos8x}8$

So,

$\displaystyle\int\sin^22x\cos^22x\,\mathrm dx=\frac18\int(1-\cos8x)\,\mathrm dx=\frac x8-\frac1{64}\sin8x+C$

Express 0.9534 as a fraction

Solnce55 [7]

Express 0.9534 as a fraction

0.9534 × 10 × 10 × 10 × 10 = 9534
1 × 10 × 10 × 10 × 10 = 10000
9534/10000

Divide by GCF:-

GCF = 2

9534 ÷ 2 = 4767
1000 ÷ 2 = 500
4767/500
^^^Improper fraction
Convert to mixed number:-

4767 ÷ 500 = 9.534

500 × 9 = 4500

4767 - 4500 = 267

9 = whole number
267 = numerator
500 = denominator

9 267/500

0.9534 = 9537/10000 = 4767/1000 = 9 267/500
