Hey guys,
I've a few more questions this time around from my problem set:
(Ignore the first question , I only need help with 2a, b,and c.)
Question:
For the first one, I assessed the inside of the inverse trigonometric function first:
sin^-1 (2/3) = 0.785
Then tan-1(.785) ~ .66577,
Likewise, for b, I got 2.14173 and undefined for c.
However, I am having trouble finding these in exact values. How would I go about doing that? For example, is sin^-1 (2/3) a common trigonometric value I should be committing to memory? Thanks again guys.
