Solve 3tan(60)+cos(60)-2tan(45)

$$3 \tan ( 60 ) + \cos ( 60 ) -2 \tan ( 45 )$$

Evaluate

$$3\sqrt{3}-\frac{3}{2}\approx 3.696152423$$

Solution Steps

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

$$3\sqrt{3}+\cos(60)-2\tan(45)$$

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

$$3\sqrt{3}+\frac{1}{2}-2\tan(45)$$

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

$$3\sqrt{3}+\frac{1}{2}-2\times 1$$

Multiply 2 and 1 to get 2.

$$3\sqrt{3}+\frac{1}{2}-2$$

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

$$3\sqrt{3}-\frac{3}{2}$$
