Solve 2sqrt{3}cospi+2sinpi)-cos(pi/3+sin)

$$2 \sqrt { 3 } \cos \pi + 2 \sin \pi ) - \cos ( \frac { \pi } { 3 } + \sin )$$

Evaluate

$$-2\sqrt{3}\approx -3.464101615$$

Solution Steps

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

$$2\sqrt{3}\left(-1\right)+2\sin(\pi )$$

Multiply 2 and -1 to get -2.

$$-2\sqrt{3}+2\sin(\pi )$$

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

$$-2\sqrt{3}+2\times 0$$

Multiply 2 and 0 to get 0.

$$-2\sqrt{3}+0$$

Anything plus zero gives itself.

$$-2\sqrt{3}$$
