`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)
In a computer, clock speed refers to the number of pulses per second generated by an oscillator that sets the tempo for the processor. Clock speed is usually measured in MHz (megahertz, or millions of pulses per second) or GHz (gigahertz, or billions of pulses per second).
