7/2 =3sin(b(pi/2))+2

Solution

\frac{7}{2} = 3 sin (b (\frac{π}{2})) + 2

Solution

b = \frac{1}{3} + 4 n, b = \frac{5}{3} + 4 n

Degrees

b = 19.09859 \dots^{\circ} + 229.18311 \dots^{\circ} n, b = 95.49296 \dots^{\circ} + 229.18311 \dots^{\circ} n

Solution steps

\frac{7}{2} = 3 sin (b (\frac{π}{2})) + 2

Switch sides

3 sin (b \frac{π}{2}) + 2 = \frac{7}{2}

Move

2

to the right side

3 sin (b \frac{π}{2}) + 2 = \frac{7}{2}

Subtract

2

from both sides

3 sin (b \frac{π}{2}) + 2 - 2 = \frac{7}{2} - 2

Simplify

3 sin (b \frac{π}{2}) + 2 - 2 = \frac{7}{2} - 2

Simplify

3 sin (b \frac{π}{2}) + 2 - 2 : 3 sin (b \frac{π}{2})

3 sin (b \frac{π}{2}) + 2 - 2

Add similar elements:

2 - 2 = 0

= 3 sin (b \frac{π}{2})

Simplify

\frac{7}{2} - 2 : \frac{3}{2}

\frac{7}{2} - 2

Convert element to fraction:

2 = \frac{2 \cdot 2}{2}

= - \frac{2 \cdot 2}{2} + \frac{7}{2}

Since the denominators are equal, combine the fractions:

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

= \frac{- 2 \cdot 2 + 7}{2}

- 2 \cdot 2 + 7 = 3

- 2 \cdot 2 + 7

Multiply the numbers:

2 \cdot 2 = 4

= - 4 + 7

Add/Subtract the numbers:

- 4 + 7 = 3

= 3

= \frac{3}{2}

3 sin (b \frac{π}{2}) = \frac{3}{2}

3 sin (b \frac{π}{2}) = \frac{3}{2}

3 sin (b \frac{π}{2}) = \frac{3}{2}

Divide both sides by

3

3 sin (b \frac{π}{2}) = \frac{3}{2}

Divide both sides by

3

\frac{3 sin ( b \frac{π}{2} )}{3} = \frac{\frac{3}{2}}{3}

Simplify

Simplify

\frac{3 sin ( b \frac{π}{2} )}{3} : sin (b \frac{π}{2})

\frac{3 sin ( b \frac{π}{2} )}{3}

Divide the numbers:

\frac{3}{3} = 1

= sin (b \frac{π}{2})

Simplify

\frac{\frac{3}{2}}{3} : \frac{1}{2}

\frac{\frac{3}{2}}{3}

Apply the fraction rule:

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

= \frac{3}{2 \cdot 3}

Multiply the numbers:

2 \cdot 3 = 6

= \frac{3}{6}
