Unit 31: Parseval’s theorem
people.math.harvard.eduThe following theorem is called the Parseval’s identity. It is the Pythagoras theorem for Fourier series. Theorem: jjfjj 2= a 0 + X1 n=1 a2 n + b 2 n: Linear Algebra and Vector Analysis Proof. The function g(x) = pa 0 2 + P 1 n=1 a ncos(nx) + P 1 n=1 b nsin(nx) agrees with f(x) …

ncert.nic.inThe theorem can also be proved by using the Pythagoras Theorem as follows: PQ2 = OP2 – OQ2 = OP2 – OR2 = PR2 (As OQ = OR) which gives PQ = PR. 2. Note also that ∠ OPQ = ∠ OPR. Therefore, OP is the angle bisector of ∠ QPR, i.e., the centre lies on the bisector of the angle between the two tangents.

www.ncert.nic.inBy Pythagoras theorem, OB = 13 Using a compass with centre O and radius OB, draw an arc which intersects the number line at the point C. Then, C corresponds to 13. Remark: We can also take OA = 2 units and AB = 3 units. Sample Question 2 : Express 0.123 in the form p q, where p and q are integers and q ≠ 0. Solution : Let x = 0.123 so, 10x = 1.23
