`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 use of extreme tempo was very common in the fast bebop jazz from the 1940s and 1950s. A common jazz tune such as  Cherokee  was often performed at quarter note equal to or sometimes exceeding 368 BPM. Some of Charlie Parker 's famous tunes (Bebop, Shaw Nuff) have been performed at 380 BPM plus.eats per minute (BPM) is a unit typically used as a measure of tempo in music and heart rate. The BPM tempo of a piece of music is conventionally shown in its score as a metronome mark, as illustrated to the right.
