Best ResponseYou've already chosen the best response.2factor out cos \[\cos(\theta)(5\sin(\theta) 3) \] now set each factor to zero and solve \[\cos(tehta) = 0~~~and~~~5\sin(\theta)  3 = 0\]

Best ResponseYou've already chosen the best response.0From your unit circle you can pick out where cosine is 0. For the sine solutions, you already have sin Θ = 0.6. Use the sin^1 button on your calculator to find Θ Θ = sin^1 (0.6) This gives an angle in the 1st quadrant. sine is also positive in the 2nd quadrant. Subtract the other solution from pi to get the angle in the 2nd quadrant. Θ = π  sin^1 (0.6)

Best ResponseYou've already chosen the best response.0we can factor out cos( \theta), so we can write: \[\Large \cos \theta \left( {5\sin \theta  3} \right) = 0\]

Best ResponseYou've already chosen the best response.2you have missed on of the key aspects of the question, you are working in radians and you should have 4 angles as the solution

Best ResponseYou've already chosen the best response.0@MTALHAHASSAN2 yes he's right. It is in radians

Best ResponseYou've already chosen the best response.2you solutions to the factor are correct.. \[\cos(\theta) = 0\] what 2 angles measure make this true, remember its in radians...

Best ResponseYou've already chosen the best response.2the domain is given as \[0 < \theta l< 2\pi\] so you should answer in radians

MTALHAHASSAN2

Best ResponseYou've already chosen the best response.0yep the answer is in radian

Best ResponseYou've already chosen the best response.2so the solutions for \[\cos(\theta) = 0\] should be straight forward the 2 angles for \[\sin(\theta) = \frac{3}{5}\] are in the 1st quadrant and 2nd quadrant

Best ResponseYou've already chosen the best response.05sin(θ)cos(θ)3cos(θ) = 0 divide by 5 sin(θ)cos(θ) 3/5cos(θ)=0 3/5=sin37(approx) sin(θ)cos(θ)sin(37)cos(θ)=0 cos(θ)[sin(θ)sin(37)]=0 either cos(θ)=0 i.e, (θ)=90 or sin(θ)sin(37)=0 i.e (θ)=37 or 143 :)

Best ResponseYou've already chosen the best response.2does that make sense..?

MTALHAHASSAN2

Best ResponseYou've already chosen the best response.0so 37 and 143 be the answer

Best ResponseYou've already chosen the best response.2so find the 1st quadrant angle for theta and then 2nd quadrant is \[\pi  \theta\]

Best ResponseYou've already chosen the best response.0the solutions are 90 = pi/2 rad 37=37pi/180 rad 143=143pi/180 rad do the calculations and get the answer in radians

Best ResponseYou've already chosen the best response.2ummm not quite... I got 0.6435011.... can you just check again you have to press 2nd to before closing the brackets then =

Best ResponseYou've already chosen the best response.2great so that is the 1st quadrant answer to the nearest hundredth now the 2nd quadrant is \[\pi  0.64\]

Best ResponseYou've already chosen the best response.2ok... so they are the values for sin now the values of cos you have \[\cos(\theta) = 0\] what angles make it true..?
