Express sin(5theta) in terms of sin(theta) and powers of sin(theta) only.

Consider the expression (cos(theta) + i*sin(theta)) 5 . (Where theta a real parameter).By De Moirve's theorem, we know this expression is equivalent to cos(5theta) + i sin(5theta).We can also apply the binom...

A ball is released from height h w.r.t. the ground. Draw a qualitative height versus time diagram of the ball bouncing in a non-ideal case.

In a non-ideal case, there will be energy loss in heat when the ball touches the ground. In particular: K n =aK n-1 , where K n-1 is the kinetic energy before the nth bounce, K n is the kinetic energy after ...
