2 AnswersMathematics1 decade agoCalculus help - Find the sensitivity?
If R denotes the reaction of the body to some stimulus of strength x , the \ sensitivity S is defined to be the rate of change of the reaction with respect to x . A particular example is that when the brightness x of a light source is increased, the eye reacts by decreasing the area R of the pupil. The experimental formula R= (35+16x^4)/(1+0.5x^4)
can be used to model the dependence of R on x when R is measured in square millimeters and x is measured in appropriate units of brightness.
Find the sensitivity corresponding to x=2
Sensitivity=?????
