Radians and Degrees 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.
z (in degrees) | 0.1 | 0.01 | 0.0001 |
|
(b) Use the table to estimate
for z in degrees. What is the exact value of this limit?
(Hint:
(c) Use the limit definition of the derivative to find
(d) Define the new functions
(e) Explain why calculus is made easier by using radians instead of degrees.

- Hyperbolic sine Function The hyperbolic sine function is defined by sinh(x)=exex2 a Sketch the graph of this function using graphical addition as in Exercise 17. b Use the definition to show that sinh(x)=sinh(x) Hyperbolic Cosine Function The hyperbolic cosine function is defined by cosh(x)=ex+ex2 a Sketch the graphs of the functions y=13ex and y=12ex on the same axes, and use graphical addition see Section 2.7 to sketch the graph of y=cosh(x). b Use the definition to show that cosh(x)=cosh(x).arrow_forward1. We know that lim as x approaches 0 (sin(x)/x) = 1 a) Explain why this limit statement implies the following approximation: (sin(x)/x) ≈ 1 if x ≈ 0. b) Rearranging this approximation, we get the smalll angle approximation: sin(x) ≈ x if x is small. Test this approximation with some small values of x )use radians). Share the result. Does this approxiamation work? c) Plot both y = sin(x) and y = x on the same axes, and show on the plot how and where the approximation is valid.arrow_forwardlim x→infinity x to the power 3/xarrow_forward
