1sin((3pi)/2)

Solution

1 sin (\frac{3 π}{2})

Solution

- 1

Solution steps

1 \cdot sin (\frac{3 π}{2})

Rewrite using trig identities:

sin (\frac{3 π}{2}) = 2 sin (\frac{3 π}{4}) cos (\frac{3 π}{4})

= 1 \cdot 2 sin (\frac{3 π}{4}) cos (\frac{3 π}{4})

Simplify

= 2 sin (\frac{3 π}{4}) cos (\frac{3 π}{4})

Use the following trivial identity:

sin (\frac{3 π}{4}) = \frac{2}{2}

Use the following trivial identity:

cos (\frac{3 π}{4}) = - \frac{2}{2}

= 2 \cdot \frac{2}{2} (- \frac{2}{2})

Simplify

2 \cdot \frac{2}{2} (- \frac{2}{2}) : - 1

= - 1
