1.0003sin(30)=1.46sin(x)

1.0003 sin (3 0^{\circ}) = 1.46 sin (x)

x = 0.34964 \dots + 36 0^{\circ} n, x = 18 0^{\circ} - 0.34964 \dots + 36 0^{\circ} n

Radians

x = 0.34964 \dots + 2 πn, x = π - 0.34964 \dots + 2 πn

Solution steps

1.0003 sin (3 0^{\circ}) = 1.46 sin (x)

sin (3 0^{\circ}) = \frac{1}{2}

sin (3 0^{\circ})

Use the following trivial identity:

sin (3 0^{\circ}) = \frac{1}{2}

sin (3 0^{\circ})

sin (x)

periodicity table with

36 0^{\circ} n

cycle:

x 0 3 0^{\circ} 4 5^{\circ} 6 0^{\circ} 9 0^{\circ} 12 0^{\circ} 13 5^{\circ} 15 0^{\circ} sin (x) 0 \frac{1}{2} \frac{2}{2} \frac{3}{2} 1 \frac{3}{2} \frac{2}{2} \frac{1}{2} x 18 0^{\circ} 21 0^{\circ} 22 5^{\circ} 24 0^{\circ} 27 0^{\circ} 30 0^{\circ} 31 5^{\circ} 33 0^{\circ} sin (x) 0 - \frac{1}{2} - \frac{2}{2} - \frac{3}{2} - 1 - \frac{3}{2} - \frac{2}{2} - \frac{1}{2}

= \frac{1}{2}

= \frac{1}{2}

1.0003 \cdot \frac{1}{2} = 1.46 sin (x)

Switch sides

1.46 sin (x) = 1.0003 \cdot \frac{1}{2}

Divide both sides by

1.46

1.46 sin (x) = 1.0003 \cdot \frac{1}{2}

Divide both sides by

1.46

\frac{1.46 sin ( x )}{1.46} = \frac{1.0003 \cdot \frac{1}{2}}{1.46}

Simplify

\frac{1.46 sin ( x )}{1.46} = \frac{1.0003 \cdot \frac{1}{2}}{1.46}

Simplify

\frac{1.46 sin ( x )}{1.46} : sin (x)

\frac{1.46 sin ( x )}{1.46}

Cancel the common factor:

1.46

= sin (x)

Simplify

\frac{1.0003 \cdot \frac{1}{2}}{1.46} : \frac{1.0003}{2.92}

\frac{1.0003 \cdot \frac{1}{2}}{1.46}

Multiply

1.0003 \cdot \frac{1}{2} : \frac{1.0003}{2}

1.0003 \cdot \frac{1}{2}

Multiply fractions:

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

= \frac{1 \cdot 1.0003}{2}

Multiply the numbers:

1 \cdot 1.0003 = 1.0003

= \frac{1.0003}{2}

= \frac{\frac{1.0003}{2}}{1.46}

Apply the fraction rule:

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

= \frac{1.0003}{2 \cdot 1.46}

Multiply the numbers:

2 \cdot 1.46 = 2.92

= \frac{1.0003}{2.92}

sin (x) = \frac{1.0003}{2.92}

sin (x) = \frac{1.0003}{2.92}

sin (x) = \frac{1.0003}{2.92}

Apply trig inverse properties

sin (x) = \frac{1.0003}{2.92}

General solutions for

sin (x) = \frac{1.0003}{2.92}

sin (x) = a \Rightarrow x = arcsin (a) + 36 0^{\circ} n, x = 18 0^{\circ} - arcsin (a) + 36 0^{\circ} n

x = arcsin (\frac{1.0003}{2.92}) + 36 0^{\circ} n, x = 18 0^{\circ} - arcsin (\frac{1.0003}{2.92}) + 36 0^{\circ} n

x = arcsin (\frac{1.0003}{2.92}) + 36 0^{\circ} n, x = 18 0^{\circ} - arcsin (\frac{1.0003}{2.92}) + 36 0^{\circ} n

Show solutions in decimal form

x = 0.34964 \dots + 36 0^{\circ} n, x = 18 0^{\circ} - 0.34964 \dots + 36 0^{\circ} n

3 tan (x) + 2 cos (x) = 0

(cos (x)) (b sin (x) - a) = 0, 0 \leq x < 2 π

cos (x) = - \frac{5}{34}

sin (3 x) = \frac{1}{2}, 0 \leq x \leq 1
