Fourier series coefficients ( a_n, b_n ).

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

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). ✔ Fourier series coefficients ( a_n, b_n )
