â k = 1 10 f ( k , n ) , {\displaystyle \sum _{k=1}^{10}f(k,n),}. n is a free variable and k is a bound variable; consequently the value of this expression depends on the value of n, but there is nothing called k on which it could depend.
2 Waist - At point specified below HPS (High Point Shoulder) or SNP (Side Neck Point). Measurement taken straight across, edge to edge. 3 Hem - Measured straight or curved along bottom edge, side seam to side seam (whichever is specified on the measurement chart). 4 Shoulder Seam - From HPS/SNP measure along the seam to the outer shoulder edge.
HP stands for Horse Power, an unit of measurement of power. The power generated by an engine is indirectly measured by measuring the power required to bring the output shaft to rest by applying brakes. This is how the the power generated by an engine is measured and rated, and hence the name Brake Horse Power (bhp).
