`sec^2x + cosec^2x`. `(tan x + cot x)^2`. As (1) = (2), the identity is proved. chaobas | College Teacher | (Level 1) Valedictorian. Posted on. (Answer #3). (tan x+cotx)^2 = (sinx/cosx + cosx/sinx)^2. = (sin^2 x + cos^x/(sinx cosx))^2. =(1/cosx. sinx)^2 [since sin^2x + cos^x= 1].
When you tap your foot to the music, you are. keeping the beat or following the structural rhythmic pulse of the music. There are. several important aspects of rhythm: â¢ DURATION: how long a sound (or silence) lasts. â¢ TEMPO: the speed of the BEAT, which can described by the number of. beats/second (or in Classical music by standard Italian terms)
The music rhythm is the beat. It is the most important element in music. It drives the music forward. It is the gasoline of music. Rhythms can be simple or complicated.
