3sin(2t)+4=1

Solution

3 sin (2 t) + 4 = 1

Solution

t = \frac{3 π}{4} + πn

Degrees

t = 13 5^{\circ} + 18 0^{\circ} n

Solution steps

3 sin (2 t) + 4 = 1

Move

4

to the right side

3 sin (2 t) + 4 = 1

Subtract

4

from both sides

3 sin (2 t) + 4 - 4 = 1 - 4

Simplify

3 sin (2 t) = - 3

3 sin (2 t) = - 3

Divide both sides by

3

3 sin (2 t) = - 3

Divide both sides by

3

\frac{3 sin ( 2 t )}{3} = \frac{- 3}{3}

Simplify

sin (2 t) = - 1

sin (2 t) = - 1

2 t = \frac{3 π}{2} + 2 πn

2 t = \frac{3 π}{2} + 2 πn

Solve

2 t = \frac{3 π}{2} + 2 πn : t = \frac{3 π}{4} + πn

2 t = \frac{3 π}{2} + 2 πn

Divide both sides by

2

2 t = \frac{3 π}{2} + 2 πn

Divide both sides by

2

\frac{2 t}{2} = \frac{\frac{3 π}{2}}{2} + \frac{2 πn}{2}

Simplify

\frac{2 t}{2} = \frac{\frac{3 π}{2}}{2} + \frac{2 πn}{2}

Simplify

\frac{2 t}{2} : t

\frac{2 t}{2}

Divide the numbers:

\frac{2}{2} = 1

= t

Simplify

\frac{\frac{3 π}{2}}{2} + \frac{2 πn}{2} : \frac{3 π}{4} + πn

\frac{\frac{3 π}{2}}{2} + \frac{2 πn}{2}

\frac{\frac{3 π}{2}}{2} = \frac{3 π}{4}

\frac{\frac{3 π}{2}}{2}

Apply the fraction rule:

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

= \frac{3 π}{2 \cdot 2}

Multiply the numbers:

2 \cdot 2 = 4

= \frac{3 π}{4}

\frac{2 πn}{2} = πn

\frac{2 πn}{2}

Divide the numbers:

\frac{2}{2} = 1

= πn

= \frac{3 π}{4} + πn

t = \frac{3 π}{4} + πn

t = \frac{3 π}{4} + πn

t = \frac{3 π}{4} + πn

t = \frac{3 π}{4} + πn
