Solve 2*(tan(45)+sin(30)-cos(60))

$$2 \times ( \tan ( 45 ) + \sin ( 30 ) - \cos ( 60 ) )$$

Evaluate

$$2$$

Solution Steps

Get the value of \tan(45) from trigonometric values table.

$$2\left(1+\sin(30)-\cos(60)\right)$$

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

$$2\left(1+\frac{1}{2}-\cos(60)\right)$$

Add 1 and \frac{1}{2} to get \frac{3}{2}.

$$2\left(\frac{3}{2}-\cos(60)\right)$$

Get the value of \cos(60) from trigonometric values table.

$$2\left(\frac{3}{2}-\frac{1}{2}\right)$$

Subtract \frac{1}{2} from \frac{3}{2} to get 1.

$$2\times 1$$

Multiply 2 and 1 to get 2.

$$2$$
