A line through the origin, rotates around the origin in such a way that the angle, ¦È, between the line and the positive x-axis changes at the rate of d¦È/dt for time t¡Ý0. Which expression gives the rate at which the slope of the line is changing?

a) d¦È/dt

b) cos¦È*d¦È/dt

c) -sin¦È*d¦È/dt

d) (1/(cos¦È)^2)*d¦È/dt

e) tan¦È*d¦È/dt
