## Pendulum Lab. Interference

Pendulum Laboratory The equations of pendulum are $T= C * \sqrt{L/g}$    (1) $T= 2\pi * \sqrt{L/g} * [1+(1/2)^2*\sin^2(x/2)+(3/4)^2*\sin^4(x/2)]$   (2) 1. For which angle is the period given by pendulum equation (2) diferrent with 1% from that given by the simplest equation (1)? You can consider just the first and second term in the sum of
