Mga Hakbang ng Solution

Evaluate trigonometric functions in the problem

$$0.9945218953682733 ^ {2} + \sin^{2}(60)$$

Kalkulahin ang 0.9945218953682733 sa power ng 2 at kunin ang 0.98907380036690274552343222349289.

$$0.98907380036690274552343222349289+\left(\sin(60)\right)^{2}$$

Kunin ang halaga ng \sin(60) mula sa talahanayan ng trigonometric values.

$$0.98907380036690274552343222349289+\left(\frac{\sqrt{3}}{2}\right)^{2}$$

Para i-raise ang \frac{\sqrt{3}}{2} sa isang power, parehong i-raise ang numerator at denominator sa power at pagkatapos ay mag-divide.

$$0.98907380036690274552343222349289+\frac{\left(\sqrt{3}\right)^{2}}{2^{2}}$$

Ang square ng \sqrt{3} ay 3.

$$0.98907380036690274552343222349289+\frac{3}{2^{2}}$$

Kalkulahin ang 2 sa power ng 2 at kunin ang 4.

$$0.98907380036690274552343222349289+\frac{3}{4}$$

Idagdag ang 0.98907380036690274552343222349289 at \frac{3}{4} para makuha ang \frac{173907380036690274552343222349289}{100000000000000000000000000000000}.

$$\frac{173907380036690274552343222349289}{100000000000000000000000000000000}$$
