`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)
Tempo is the number of beats per minute (or bpm). Rhythm, at least in Ask the DJ parlance, is the beat's structure. For instance, ska doesn't beat the same way as salsa: their rhythms are different.
