We show the limit of sin(kx)/x as x goes to 0 is equal to k, even when k=0. To evaluate this trigonometric limit, we need to remember the limit of sin(x)/x with x approaching 0, which is a fundamental trigonometric limit equal to 1! If we remember this, we'll be able to solve the problem in short order by multiplying by k/k. #Calculus1 #apcalculus Limit of sin(2x)/x as x approaches 0: • Limit of sin(2x)/x as x approaches 0 | Cal...
