HELP! For sin(θ) = -0.4321, 0 ≤ θ ≤ 360°. a)How many solutions are possible? b) In which quadrants would you find the solutions? c) Determine the reference angle for this equation to the nearest degree. d) Determine all the solutions to the equation to the nearest degree.

OpenStudy (shamim):

i know in third n fourth quadrunt sin is negative

OpenStudy (shamim):

we know sin theta=oposit/hypotenuse

OpenStudy (princeharryyy):

2 solutions 3rd and 4rth may be around (360-26 deg) and 206 deg

@Katieholmes

OpenStudy (princeharryyy):

r u dere @Katieholmes

OpenStudy (anonymous):

yes

OpenStudy (princeharryyy):

were u able to solve ???

OpenStudy (princeharryyy):

or do i need 2 xplain?

OpenStudy (anonymous):

ummmmm so sin of -.4321= -26 or +26

OpenStudy (princeharryyy):

may i ask u a simple question

OpenStudy (anonymous):

so then 180+26 and 360-26 would gif the ref angles?

OpenStudy (anonymous):

sure

OpenStudy (princeharryyy):

are u familiar with the curves

OpenStudy (anonymous):

no I havent done that yet

OpenStudy (anonymous):

ive done a,b and c I just need to know how to solve for d

OpenStudy (princeharryyy):

so then 180+26 and 360-26 are solutions of the equstion are ur answers @Katieholmes

OpenStudy (anonymous):

okay awesome thank you

OpenStudy (princeharryyy):

welcome go thru curves :)))
