Errors are independent and normally distributed (for justification of least squares).

Voltage ( V(t) ) for ( t \ge 0 ).

Best‑fit line ( y = a + bx ) in the least‑squares sense. fundamental applied maths solutions

Dirichlet conditions hold (finite jumps, finite extrema).

Residuals: ( 2.1 - (1.233+1.35)= -0.483 ); ( 3.9 - (1.233+2.70)= -0.033 ); ( 5.8 - (1.233+4.05)= 0.517 ). Sum of residuals ≈ 0 (rounding). ✔ Dirichlet conditions hold (finite jumps, finite extrema)

If you need solutions for a specific problem set (e.g., from Kreyszig , Strang , or Logan ), please provide the and I will produce a matching write‑up.

Fourier series coefficients ( a_n, b_n ). ✔ If you need solutions for a specific problem set (e

For ( n=1 ): coefficient ( 2 ) → matches sawtooth wave. ✔ At ( t=\pi/2 ): series gives ( 2 - 1 + 2/3 - 1/2 + \dots = \pi/2 ) (Leibniz series). ✔
