Accidents have been rare, but have happened. Faculty and staff exercise great care to minimize and, where possible, eliminate all potential hazards. Additionally, minimization of risks requires that students come well prepared for each class and are attentive. -------------------------------- d(eax) = a∙eax d(eau) = a∙eau∙du ln(eax) = ax log10(10b) = b ln(10) = 2.303 log(10) = 1 ln(1) = 0 log(1) = 0 ln (0) = ─ ∞ log(0) = ─ ∞ ln K = 2.303 log K {dx/x} = d (ln x) = fractional change in x (∂x/∂y)z (∂y/∂z)x (∂z/∂x)y = ─ 1
