View Solution. Answer link. This limit gives a 0/0 indeterminate form but you can use de l'Hospital Rule to get the result of 4/6. → = 1. This answer is indeterminate and therefore we would use L'Hôpital's rule which says to treat the numerator and denominator as separate functions and to take the derivative of each one like
This limit is indeterminate since direct substitution yields #0/0#, which means that we can apply L'Hospital's rule, which simply involves taking a derivative of the numerator and the denominator. On completing the integration, the answer should be: ∫ sin 2 x cos 4 x d x = x 16 + sin 2 x 64 − sin
Both numerator and denominator tend to zero, and they are continuous and differentiable, so L'Hopital's rule applies. The calculator will use the best method available so try out a lot of different types of problems.mil . (sin2x + cos2x) = 1.5. Q 3.
