(1)(1-30/100+1/(2pi)(sin(2pi)(30/100)))

(1) (1 - \frac{30}{100} + \frac{1}{2 π} (sin (2 π) (\frac{30}{100})))

\frac{7}{10}

Decimal Notation

0.7

Solution steps

(1) (1 - \frac{30}{100} + \frac{1}{2 π} (sin (2 π) (\frac{30}{100})))

= 1 \cdot (1 - \frac{30}{100} + \frac{1}{2 π} sin (2 π) \frac{30}{100})

Rewrite using trig identities:

sin (2 π) = 0

sin (2 π)

sin (2 π) = sin (0)

sin (2 π)

Rewrite

2 π

2 π + 0

= sin (2 π + 0)

Apply the periodicity of

sin

sin (x + 2 π) = sin (x)

sin (2 π + 0) = sin (0)

= sin (0)

= sin (0)

Use the following trivial identity:

sin (0) = 0

sin (0)

sin (x)

= 0

= 1 \cdot (1 - \frac{30}{100} + \frac{1}{2 π} \cdot 0 \cdot \frac{30}{100})

Simplify

1 \cdot (1 - \frac{30}{100} + \frac{1}{2 π} \cdot 0 \cdot \frac{30}{100}) : \frac{7}{10}

1 \cdot (1 - \frac{30}{100} + \frac{1}{2 π} \cdot 0 \cdot \frac{30}{100})

\frac{30}{100} = \frac{3}{10}

\frac{30}{100}

Cancel the common factor:

10

= \frac{3}{10}

\frac{1}{2 π} \cdot 0 \cdot \frac{30}{100} = 0

\frac{1}{2 π} \cdot 0 \cdot \frac{30}{100}

\frac{30}{100} = \frac{3}{10}

\frac{30}{100}

Cancel the common factor:

10

= \frac{3}{10}

= 0 \cdot \frac{1}{2 π} \cdot \frac{3}{10}

Multiply fractions:

\frac{a}{b} \cdot \frac{c}{d} = \frac{a \cdot c}{b \cdot d}

= 0 \cdot \frac{1 \cdot 3}{2 \cdot 10 π}

\frac{1 \cdot 3}{2 π 10} = \frac{3}{20 π}

\frac{1 \cdot 3}{2 π 10}

Multiply the numbers:

1 \cdot 3 = 3

= \frac{3}{2 \cdot 10 π}

Multiply the numbers:

2 \cdot 10 = 20

= \frac{3}{20 π}

= 0 \cdot \frac{3}{20 π}

Apply rule

0 \cdot a = 0

= 0

= 1 \cdot (- \frac{3}{10} + 1 + 0)

Add the numbers:

1 + 0 = 1

= 1 \cdot (- \frac{3}{10} + 1)

Join

- \frac{3}{10} + 1 : \frac{7}{10}

- \frac{3}{10} + 1

Convert element to fraction:

1 = \frac{1 \cdot 10}{10}

= \frac{1 \cdot 10}{10} - \frac{3}{10}

Since the denominators are equal, combine the fractions:

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

= \frac{1 \cdot 10 - 3}{10}

1 \cdot 10 - 3 = 7

1 \cdot 10 - 3

Multiply the numbers:

1 \cdot 10 = 10

= 10 - 3

Subtract the numbers:

10 - 3 = 7

= 7

= \frac{7}{10}

= 1 \cdot \frac{7}{10}

Multiply:

1 \cdot \frac{7}{10} = \frac{7}{10}

= \frac{7}{10}

= \frac{7}{10}
