Løsningsvejledning

Get the value of \tan(0) from trigonometric values table.

$$\left(0-\frac{1}{3}\sin(270)\right)^{\frac{1}{2}}$$

Get the value of \sin(270) from trigonometric values table.

$$\left(0-\frac{1}{3}\left(-1\right)\right)^{\frac{1}{2}}$$

Multiplicer \frac{1}{3} og -1 for at få -\frac{1}{3}.

$$\left(0-\left(-\frac{1}{3}\right)\right)^{\frac{1}{2}}$$

Det modsatte af -\frac{1}{3} er \frac{1}{3}.

$$\left(0+\frac{1}{3}\right)^{\frac{1}{2}}$$

Tilføj 0 og \frac{1}{3} for at få \frac{1}{3}.

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