Which of the following in blood is NOT involved in triggering  chemoreceptors that would enable an animal to regulate or adjust its respiratory pattern?

Establish the identity (10 points) (sin A + cos B )2 + (cos B + sin A)(cos B – sin  A) = 2(cos B)(sin A + cos B)

(10 points) Find the exact value of: cos(tan-1(125)+cos-1(-45))

(2 points each)  Find all solutions for the equations below (write the general solutions for each).  No calculator! a) sec(x)=2 b) cot(x)=33

Evaluate  Leave your answer in polar form.  (use Demoivre’s theorem)If you see an error in the formatting, you are evaluating the 8th power of the same complex number from the previous problem.

  Solve the following equation for ALL SOLUTIONS:   (10 points) tan(x) = 2 sin(x)
