`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)
