for questions 89 use a caculator to find the approximate val

for questions 8-9, use a caculator to find the approximate value, express the value in radian

for questions 10-14 find the exact value

for questions 15-16 find qn algebraic expression equivalent to the following expressions

For questions 8-9, use a calculator to find the approximate value. Express the result in radians: 8. sin (-0.23) Answer 9. tan (17.8) Answer For questions 10 14, find the exact value: 10. Cos (0) Answer: 11. Sin-11- Answer 12. Tan Answer 13. sin Arccos 2 Answer:

8)sin^-1(-0.23)=-0.232 radians

9)tan^-1(17.8)=1.515

10)cos^-1(0)=/2

11)sin^-1(-2 /2)=-/4

12)tan^-1(3 /3)=/6

13)sin[arccos(1/2)]

=sin[arcsin(3 /2)]

=3 /2

14)tan(arcsin(0.43))

=tan(arctan(0.43/(1²-0.43²)))

=0.43/(1-0.43²)

=0.47628
