Solve cos30^circ+sin90^circ=

$$\cos 30 ^ { \circ } + \sin 90 ^ { \circ } =$$

Evaluate

$$\frac{\sqrt{3}}{2}+1\approx 1.866025404$$

Solution Steps

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

$$\frac{\sqrt{3}}{2}+\sin(90)$$

Get the value of \sin(90) from trigonometric values table.

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

To add or subtract expressions, expand them to make their denominators the same. Multiply 1 times \frac{2}{2}.

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

Since \frac{\sqrt{3}}{2} and \frac{2}{2} have the same denominator, add them by adding their numerators.

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