ok how about this one: f(x)=12x/sinx+cosx find f'(-pie) this is what i did: 12(-pi)/(0+(-1)) = 12pi is that right what am i doing wrong and what would be the answer

108/87 = 1.2414 = 124.14% Then you subtract 100% of what you got because that was your original number 124.14% - 100% = 24.14% Its 24.14% increase

Another way you could do it is do 95/80 = 1.1875 x 100 = 118.75 Then subtract 100% from that 118.75% - 100% = 18.75% whoch rounds up to 18.8%
