Solve sen (x/2)= sen x - sen 2

Evaluate

se n \times \frac{x}{2} = se n x - se n \times 2

Multiply the terms

More Steps

\frac{es n x}{2} = se n x - se n \times 2

Simplify

More Steps

\frac{es n x}{2} = es n x - 2 es n

Multiply both sides of the equation by LCD

\frac{es n x}{2} \times 2 = (es n x - 2 es n) \times 2

Simplify the equation

es n x = (es n x - 2 es n) \times 2

Simplify the equation

More Steps

es n x = 2 es n x - 4 es n

Move the variable to the left side

es n x - 2 es n x = - 4 es n

Subtract the terms

More Steps

- e n s x = - 4 es n

Divide both sides

\frac{- e n s x}{- e n s} = \frac{- 4 es n}{- e n s}

Divide the numbers

x = \frac{- 4 es n}{- e n s}

Solution

More Steps

x = 4
