Answer:
((√2)/2, -(√2)/2)
Step-by-step explanation:
The coordinates of the point on the unit circle for any angle θ are ...
... (x, y) = (cos(θ), sin(θ))
For the angle -π/4, the coordinates are ...
... (cos(-π/4), sin(-π/4)) = ((√2)/2, -(√2)/2)
Increased by 5%
1930*5/100= 96.5
1930+96.5=2026.5
Further increase by 15%
2026.5*15/100=303.975
2026.5+303.975=2330.475
To 2DP= 2330.48
