Solve pi*cos(pi)+3sin(pi)-pi*cos(pi)-sin(pi)/1

$$\frac{ \pi \times \cos ( \pi ) +3 \sin ( \pi ) - \pi \times \cos ( \pi ) - \sin ( \pi ) }{ 1 }$$

Evaluate

$$0$$

Solution Steps

Get the value of \cos(\pi ) from trigonometric values table.

$$\frac{\pi \left(-1\right)+3\sin(\pi )-\pi \cos(\pi )-\sin(\pi )}{1}$$

Get the value of \sin(\pi ) from trigonometric values table.

$$\frac{\pi \left(-1\right)+3\times 0-\pi \cos(\pi )-\sin(\pi )}{1}$$

Multiply 3 and 0 to get 0.

$$\frac{\pi \left(-1\right)+0-\pi \cos(\pi )-\sin(\pi )}{1}$$

Anything plus zero gives itself.

$$\frac{\pi \left(-1\right)-\pi \cos(\pi )-\sin(\pi )}{1}$$

Get the value of \cos(\pi ) from trigonometric values table.

$$\frac{\pi \left(-1\right)-\pi \left(-1\right)-\sin(\pi )}{1}$$

Combine \pi \left(-1\right) and -\pi \left(-1\right) to get 0.

$$\frac{0-\sin(\pi )}{1}$$

Get the value of \sin(\pi ) from trigonometric values table.

$$\frac{0-0}{1}$$

Subtracting 0 from itself leaves 0.

$$\frac{0}{1}$$

Anything divided by one gives itself.

$$0$$

Factor

$$0$$
