Two parallel chords of length 24 cm and 10 cm which lies on opposite
sides of a circle are 17 cm apart. Calculate the radius of the circle
to the nearest whole number.
in eac of the following problems you are
given a function on the interval −π<x<π.
Sketch several periods of the corresponding
periodic function of period 2π. Expand the
periodic function in a sine−consine Fourier
series.
F(x) = { _0 ^(x+π) _(0<x<π) ^(−π<x<0)
A block of mass 2.0kg resting on a smooth horizontal plane is acted
upon simultaneously by two forces 10N due north and 10N due east.
The magnitude of the acceleration produce by the force on the block.
