Find the complete solution (to the nearest tenth) if sin𝛳= -.98544973 and 0≤𝛳≤2π.

Answer 1

@mathmale please help.

Answer 2

first use your calculator to find the angles whose sine is 0.98544973 ( set angles to radians)

Answer 3

can you do that? the required key will be either sin-1 or arcsin

Answer 4

r u there?

Answer 5

yes i was trying to find free TI 84 calculator online to use

Answer 6

so press sin-1(0.98544973 ?

Answer 7

I got 1.4

Answer 8

is that right? @welshfella

Answer 9

thanks I got it now @welshfella
it's 1.4+π =4.5
-1.4+2π=4.9
