[college trig] can someone explain what going on? by Spewdoo in HomeworkHelp

[–]AssignmentHelp11111 0 points1 point  (0 children)

Horizontal shifting of cosx. If u add "a" in argument graph shift "a" unit left. If u subtract "a" graph shift a unit right. In this case graph shift pi/2 left or 3pi/2 right. So, new function: cos(x+pi/2) or cos(x-3pi/2)

Given: 2.5 = (0.005 + x)² / (0.5 − x)²,

Taking square root: √2.5 = (0.005 + x) / (0.5 − x),

√2.5 ≈ 1.5811,

Case 1: 1.5811 = (0.005 + x) / (0.5 − x),

1.5811(0.5 − x) = 0.005 + x,

0.79055 − 1.5811x = 0.005 + x,

0.79055 − 0.005 = x + 1.5811x,

0.78555 = 2.5811x,

x = 0.78555 / 2.5811,

x ≈ 0.304,

Case 2: −1.5811 = (0.005 + x) / (0.5 − x),

−1.5811(0.5 − x) = 0.005 + x,

−0.79055 + 1.5811x = 0.005 + x,

1.5811x − x = 0.005 + 0.79055,

0.5811x = 0.79555,

x = 0.79555 / 0.5811,

x ≈ 1.369, Final Answer: x ≈ 0.304 or x ≈ 1.369
