15009.81sin(pi)

1500 \cdot 9.81 \cdot sin (π)

0

Solution steps

1500 \cdot 9.81 sin (π)

= 1500 \cdot \frac{981}{100} sin (π)

Use the following trivial identity:

sin (π) = 0

sin (π)

sin (x)

periodicity table with

= 0

= 1500 \cdot \frac{981}{100} \cdot 0

Simplify

1500 \cdot \frac{981}{100} \cdot 0 : 0

1500 \cdot \frac{981}{100} \cdot 0

Multiply fractions:

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

= 0 \cdot \frac{981 \cdot 1500}{100}

\frac{981 \cdot 1500}{100} = 14715

\frac{981 \cdot 1500}{100}

Multiply the numbers:

981 \cdot 1500 = 1471500

= \frac{1471500}{100}

Divide the numbers:

\frac{1471500}{100} = 14715

= 14715

= 0 \cdot 14715

Apply rule

0 \cdot a = 0

= 0

= 0
