Solve 4*0626+3^2-2*0626*3*cos(30)

$$4 \times 0626+ { 3 }^{ 2 } -2 \times 0626 \times 3 \times \cos ( 30 )$$

Evaluate

$$9$$

Solution Steps

Multiply 4 and 0 to get 0.

$$0\times 626+3^{2}-0\times 2\times 3\times 626\cos(30)$$

Multiply 0 and 626 to get 0.

$$0+3^{2}-0\times 2\times 3\times 626\cos(30)$$

Calculate 3 to the power of 2 and get 9.

$$0+9-0\times 2\times 3\times 626\cos(30)$$

Add 0 and 9 to get 9.

$$9-0\times 2\times 3\times 626\cos(30)$$

Multiply 0 and 2 to get 0.

$$9-0\times 3\times 626\cos(30)$$

Multiply 0 and 3 to get 0.

$$9-0\times 626\cos(30)$$

Multiply 0 and 626 to get 0.

$$9-0\cos(30)$$

Get the value of \cos(30) from trigonometric values table.

$$9-0\times \frac{\sqrt{3}}{2}$$

Anything times zero gives zero.

$$9-0$$

Subtract 0 from 9 to get 9.

$$9$$
