Approach when limit depends on direction•>> value_left = limit(tan(x),x,pi/2,'left'),•>> value_right = limit(tan(x),x,pi/2,'right')•Conclusions?•MATLAB's numeric engine gives a finite, albeit verylarge, value. Big mistakes could result if this wereused in subsequent calculations.•The symbolic engine gives both values correctly, butto get them you must add the additional argumenttelling MATLAB from which direction to approach thelimit ('left' beginning with smaller values of x andincreasing to the limit, and 'right' beginning with largervalues of x and decreasing to the limit.142
Review Questions•What command do you use to tell MATLAB that r, sand t are to be symbolic?•>> syms r s t•What command do you use to differentiate sin 2 t ?•>> diff(sin(t)^2,t)•What command do you use to integrate e s from 0 to r?•>> int(exp(s),s,0,r)•What command do you use to evaluate the aboveintegral for r = π/2?•>> subs(int(exp(s),s,0,r),r,pi/2)143
