algebra precalculus - How can I find this limit? limxto0left(fracxcsc(2x)3cos(5x)right)



limx0(xcsc(2x)3cos(5x))




My attempt was just turning csc to 1/sin, how can I solve this


Answer



for x reaching 0 sinx=x



then



limx0xsinx=1



limx0cosx=1




So your limit is equal to 16 if I'm not mistakening
