1.

𝑦

∝= tan−1 ( )

𝑥

∝= tan−1 (

10

)

20

∝= 26. 60

𝑟 = √𝑥 2 + 𝑦 2

𝑟 = √202 + 102

𝑟 = 22.4 𝑢𝑛𝑖𝑡𝑠

𝑥

𝛽 = tan−1 ( )

𝑦

20

𝛽 = tan−1 ( )

10

𝛽 = 63. 40

2.

𝑥 = √𝑟 2 − 𝑦 2

= √152 + 102

𝑥 = 11.2 𝑢𝑛𝑖𝑡𝑠

10

)

∝= tan−1 (

11.2

∝= 41. 80

𝑥

𝛽 = tan−1 ( )

𝑦

𝛽 = tan−1 (

11.2

)

10

𝛽 = 48. 30

3.

𝑦 = √𝑟 ...
