Evaluate trigonometric functions in the problem

$$\frac{500 \cdot {(8)} ^ {2}}{2} + {(500)} {(98)} \cdot 0.9396926207859084$$

Tātaihia te 8 mā te pū o 2, kia riro ko 64.

$$\frac{500\times 64}{2}+500\times 98\times 0.9396926207859084$$

Whakareatia te 500 ki te 64, ka 32000.

$$\frac{32000}{2}+500\times 98\times 0.9396926207859084$$

Whakawehea te 32000 ki te 2, kia riro ko 16000.

$$16000+500\times 98\times 0.9396926207859084$$

Whakareatia te 500 ki te 98, ka 49000.

$$16000+49000\times 0.9396926207859084$$

Whakareatia te 49000 ki te 0.9396926207859084, ka 46044.9384185095116.

$$16000+46044.9384185095116$$

Tāpirihia te 16000 ki te 46044.9384185095116, ka 62044.9384185095116.

$$62044.9384185095116$$

Tauwehe

$$\frac{3361 \cdot 46150653390739}{2 ^ {11} \cdot 5 ^ {13}} = 62044\frac{2346046273792}{2500000000000} = 62044.93841850952$$
