The fundamental limit assumes that x is measured in radians. Suppose you assume that x is measured

Question:

The fundamental limit 

assumes that x is measured in radians. Suppose you assume that x is measured in degrees instead of radians. 

(a) Set your calculator to degree mode and complete the table.

(b) Use the table to estimate

for z in degrees. What is the exact value of this limit?

(c) Use the limit definition of the derivative to find d/dz[sin z] for z in degrees.

(d) Define the new functions S(z) = sin cz and C(z) = cos cz where c = π/180. Find S(90) and C(180). Use the Chain Rule to calculate d/dz[S(z)].

(e) Explain why calculus is made easier by using radians instead of degrees.
