Text Transcription:

r(t)=4 cos ti + 4 sin tj, t=pi/4

Step-by-Step Solution:

Step 1 of 5) Inverse Hyperbolic Functions The inverses of the six basic hyperbolic functions are very useful in integration (see Chapter 8). Since d(sinh x)>dx = cosh x 7 0, the hyperbolic sine is an increasing function of x. We denote its inverse by
